Welcome to watch Mojo.

And today we're counting down our picks for the top 20 unsolved murder mysteries.

For this list, we're looking at the most high profile and mysterious unsolved murders.

Number 20 Ken Rex McIlroy Ken Rex McIlroy was by no means the nicest man.

In fact, this town bully from Skidmore, Missouri, was indicted 21 times in his life, including for arson and assault.

In 1980 he shot and injured 70 year old grocer Ernest Bowen camp, but was able to appeal the conviction.

He immediately went back and threatened to kill Bowen camp, but he never got the chance.

On July 10th, 1981 while sitting in his pickup truck with his wife, McIlroy was shot twice from two different guns.

Ah, crowd of up to 46 people looked on.

No one called an ambulance, and everyone except his wife claimed to have not seen the shooters.

In the end, no one was charged.

Number 19.

The lake bottom murders are next.

Entry is like something out of a horror movie.

On June 5th 1962 teenage couples were camping near Finland's like bottom.

Three of them were stabbed and bludgeoned to death, while the fourth, Neil's William Gustafson, was injured.

There were several suspects, including kiosk keeper Carl Valdemar, Elstrom said, to have cut down tents in the past, and he drowned himself in the lake in 1969.

Another was a man named Hence Asman, who turned up in a hospital the next day with bloody clothes.

In 2004 police arrested the survivor, Gustafson, but he was later acquitted.

The case fascinates fins to this day and finish heavy metal band Children of bottom named themselves after the mystery number 18 The Lizzie Borden Ax Murders.

On the morning of August 4th, 18 92 Lizzie Borden discovered that both her parents had been murdered.

Both her father and stepmother had been repeatedly struck in the head with a sharp instrument.

Lizzie became the prime suspect after providing police with contradictory accounts.

A few days after the murders, she was even witnessed burning address in the kitchen stove.

She was arrested and tried in a sensational landmark trial, but was acquitted due to circumstantial evidence.

Others suspected of the murder include Lizzie, Sister Emma and her maternal uncle John Morse, who had slept in the house the night before.

Number 17.

The boy in the box 1957.

Ah boy was found naked, lying face up inside a cardboard box in the woods near Philadelphia.

He'd been wrapped in a blanket and his arms were folded across his stomach.

Investigators determined that he was 4 to 5 years old and had been killed by several blows to the head.

His entire body was covered in bruises.

Ah, woman with a history of mental illness came forward and claimed that her mother had bought the boy from his parents and abused him for years.

However, police couldn't confirm her tail, and neither the boy nor the murderer was ever identified.

Number 16 the mad butcher of Kingsbury Run, also known as the Cleveland Torso Murderer.

This serial killer murdered at least 12 people in the Cleveland area in the 19 thirties.

There were also other possible victims.

In the twenties, forties and fifties, almost all were beheaded and dismembered, with several never identified because their heads were never found and because many were drifters or members of the working poor.

Although the case was reviewed by Eliot Ness the man who put Al Capone behind bars.

No suspects were ever charged.

Some theories have even claimed that there was no single butcher but rather several different individual murderers.

Number 15.

Bob Crane When Hogan's Heroes star Bob Crane was found bludgeoned to death in his Arizona home in 1978 suspicion immediately turned to his friend John Henry Carpenter, a video equipment salesman.

Cranes extensive home video collection showed that the two were rather close, filming their sexcapades with various women together.

It was like a mad scientist who dealt in photographs of women.

Carpenter had been with him the night before and, according to Crain's son, Crane, had planned to end their friendship.

There were even stains on Carpenter's car door that matched cranes blood type.

However, insufficient evidence meant that Carpenter was let go.

The case was reopened in 1990 Carpenter went to trial four years later but was acquitted.

Number 14 the West Mesa bone collector, as a woman walked her dog in the west Mesa of Albuquerque, New Mexico, on February 2nd 2009.

She stumbled across this awful find the remains of 11 women and a fetus, which had been buried in the bank oven.

Arroyo.

Many of these women were Hispanic, and most were caught up in drugs and prostitution at the time of their disappearances.

3 to 6 years earlier, police linked these serial murders with the area's yearly state fair, which drew prostitutes to the area in large numbers.

But the crimes remain unsolved, but the families aren't the only ones frustrated.

This was one of the most horrific crimes in the history of our city, and there's been no resolution toe what has happened here.

They are suspected to have been the work of a serial killer.

Number 13 the Chicago Tylenol Murders.

Chicago was gripped with fear in late 1982 when seven locals died after taking Tylenol capsules that have been laced with cyanide.

We've been receiving calls about once every 15 seconds.

A man named James William Lewis wrote to Johnson and Johnson, saying that he was behind them and would stop for $1 million.

But since he was in New York the whole time, he was only charged with extortion.

Johnson and Johnson was applauded for its response, and tamper proof seals became common practice when copycat crimes occurred afterward.

A nationwide search is underway today to find a man and a woman wanted for questioning in the Tylenol murders.

However, even with the support of the government and a huge corporation, the person who really masterminded the poisonings was never found.

Number 12 The Highway of Tears.

The Highway of Tears is a 450 mile long stretch of road between Prince George and Prince Rupert and British Columbia, Canada.

From 1969 to 2011 At least 18 women were murdered along this highway, although it is estimated that the real number, maybe in the dozens and they're still investigating.

But if there's no leads and it's pretty much not a priority, so it's disheartening to the families many of them were in their teens, a disproportionate number of them were indigenous.

Ah, fact that has led some critics to accuse the investigating police of racism.

Although a few victims have been linked to a convicted serial killer named Bobby Jack Fowler, there's still no explanation for the other murders hitting a dead end.

The case is seemingly a road to nowhere.

Number 11 the alphabet murders, also known as the double initial murders.

The alphabet murders transpired in New York state during the early 19 seventies.

There were three victims aged 10 or 11.

Carmen Cologne, Wanda Walk, a Wits and Michelle Nyanza.

Each girl was sexually assaulted before being strangled and was found in a town, starting with the same initial as their names.

Cologne in Churchville, Walk a Wits and Webster and My Enza in Mass.

Adan.

And strangely, each girl came from similar backgrounds.

They all had learning disabilities, were Roman Catholic and came from single parent homes.

This case was later connected to a series of similar murders in California for which Joseph Naso was convicted and sentenced to death.

But his DNA didn't match the samples found on the victims.

Number 10 Amber Hagerman, While the Amber in Amber Alert does stand for America's missing broadcast emergency response, it was actually originally named for Amber Hagerman.

The nine year old was abducted while riding her bike in Arlington, Texas, on January 13th, 1996.

Just four days later, her body was discovered in a storm drainage ditch, and her killer still hasn't been found.

The outcry in response to this tragedy led to tougher laws for child abductors and sex offenders, with Bill Clinton signing the Amber Hagerman Child Protection Act into law, which created the national sex offender registry, and Amber desperately needs justice.

Number nine.

The hint.

Erkki Fake murders This farmstead in Germany was home to one of the country's strangest murder mysteries.

On March 31st, 1922 the family living at Hunter Kaifeng was murdered along with their made.

The crime scene suggested that four of the six had been led to the barn and killed one by one.

Among the victims were seven year old Sicilia, Gruber and her two year old brother, Joseph.

Just days before the massacre, their grandfather, Andreas Gruber, discovered footprints in the snow leading to the farm, but none leading back away.

Although police questioned over 100 suspects, nobody was ever convicted.

Number eight Tupac and the Notorious B.

I.

G ah fierce rivalry between East Coast and West Coast rappers led to two of their biggest stars being gunned down.

On September 7th, 1996 Tupac was shot four times at a red light on a Las Vegas street after leaving a Mike Tyson boxing match with death row records.

CEO Suge Knight.

The prime suspect was Orlando Anderson, a member of the Southside Crips.

Months later, Biggie was also shot four times at a red light while traveling in Los Angeles.

It's been theorized that night had biggie killed in revenge for two packs murder.

However, thanks to inconclusive leads and uncooperative witnesses, no one was ever charged for either number seven.

Jimmy Hoffa.

Ah, union activists.

Since his teens, Jimmy Hoffa became the president of the International Brotherhood of Teamsters in 1958.

His role with the Teamsters led him to organized crime, however, and he was even sentenced to prison for jury tampering and fraud.

This connection may have led to his subsequent disappearance.

Hoffa was last seen in the parking lot of the Max's Red Fox restaurant on July 30th, 1975.

Hoffa had allegedly been there to meet with two members of the Mafia.

He was officially declared dead in 1982 and his body has yet to be found, although there is no shortage of rumors as to the circumstances surrounding his death.

Number six.

The ax Man of New Orleans between 1918 and 1919 a serial killer simply known as the ax man terrorized New Orleans theatrics.

Man is believed to have murdered eight people, although it is speculated there were several more victims.

Almost all the confirmed victims were Italian Americans and killed with an ax.

On March 13th, 1919 a person claiming to be the ax man had a letter published in the newspaper claiming he or she was not human but rather quote a demon from the hottest hell.

The murder suddenly stopped shortly thereafter, and the ax man's identity was never discovered.

He or she was apparently a jazz fan and promised to spare anyone whose home had a jazz band in full swing.

Number five Jon Benet Ramsey.

In the late nineties, this murder gripped the nation and gave rise to numerous theories.

Six year old beauty queen JonBenet Ramsey was found dead in the basement of her Colorado home on the day after Christmas.

Her skull was broken and she'd been strangled with a garage that morning.

Her mother, Patsy, had discovered a ransom note and contacted police due to the unusual details in the note, Patsy and her husband, John, immediately came under suspicion for someone Thio accuse you.

It's just you can't believe that that would happen.

The book says the parents always did it.

However, forensic evidence cleared them of involvement.

Criticism has since focused on shoddy police work.

At the scene in 2006 elementary schoolteacher John Mark Karr claimed to have killed her, but the DNA found on JonBenet's body was not a match number four.

The Long Island serial killer.

Ah, present day Jack the Ripper.

This unidentified serial killer is said to have murdered at least 10 people and dumped them along Long Island's Ocean Parkway.

The victims include eight women, a man and a toddler, with the earliest killed in 1997.

Some were wrapped up inside burlap sacks.

Three remain unidentified.

Their remains were discovered in 2010 in 2011 Often choosing people who advertise themselves as sex workers on Craigslist, the so called Gilgo killer has remained nameless since the first victim surfaced.

It's been speculated that the killer may have had some knowledge of law enforcement and how to best evade capture.

Number three The Black Dahlia.

Perhaps the most striking detail about 22 year old Elizabeth Short's gruesome murder in 1947 was that her mouth was slashed at either edge, giving the false impression of a wide smile.

Her body was found naked and cut in half of the waste in a vacant lot in Leimert Park, Los Angeles, coverage was sensational and even shamed short for her relationships with men.

She became known as the Black Dahlia, and her unsolved murder sparked theories, books and films in the years after her death.

Although police identified more than 150 suspects, the perpetrator was never found.

Number two, the Zodiac killer.

The Zodiac killer began taunting authorities in the late 19 sixties when a string of similarly murdered victims surfaced in Northern California.

He sent letters in cryptic puzzles to police and media, naming himself Zodiac and daring them to catch him.

While he's known to have killed at least five people, he claimed to be responsible for the murder of up to 37.

His letters included four Crypto Grams.

Once solved, one stated that he was collecting slaves for the afterlife.

The others remain unsolved.

While there were several suspects and even a Hollywood movie, the Zodiac killer's identity still remains a mystery.

Number one Jack the Ripper The murder of five prostitutes in London's White Chapel district in 18 88 has become one of the most infamous unsolved crime mysteries in history.

The victims were found with their throats slashed and their abdomens mangled.

Three had internal organs removed.

This led to the belief that the killer may have been well educated or even a surgeon.

At the time, the media and authorities received a barrage of letters that claimed to be from the killer.
