True Crime On This Day May 30th

May 30th

On May 30th in true crime, murder in California, cold cases, assassination, bomb in Los Angeles, unsolved crimes, and disappearances.


In St. Louis, Missouri, 41-year-old Sergeant William Campbell was shot and killed when he stepped foot outside of the St. Louis Police Station.

A suspect had broken into Campbell’s police car and removed a shotgun which he used to shoot Campbell in the chest with.

Other officers shot the suspect dead as he attempted to escape. Campbell had been active with the service for over 12 years.


In Berrien County, Georgia, 23-year-old air traffic controller Mary Susan Humphrey disappeared after leaving the Grego’s nightclub in the early hours of the morning.

Humphrey worked at the Moody Air Force Base but lived off-site near Walker’s Crossing. On Sunday, June 15th 1980, her body was discovered on a dirt road by a group of men and their hunting dogs.

A former boyfriend was later tried for the murder but was found innocent. Despite numerous leads since, no suspect has ever been caught.


In Chittagong, Bangladesh, President Ziaur Rahman was shot dead by a group of rebel army officers. Six bodyguards and two aides were also killed in the attack.

Prior to the assassination, Rahman was criticised for his ruthless treatment of the army opposition despite his overall popularity with the public.

The attack on the president had been planned and executed by Major General Muhammed Manzur. Reports later claimed that the president had been shot while wearing his bedclothes. More than two-million people attended his funeral.


In Los Angeles, four days after the Swiss Bank Corporation bombing, another bomb was placed in front of the Canada cargo building at Los Angeles International Airport.

It was discovered before it exploded and defused by members of the Los Angeles Police Department’s bomb squad.

As in the May 26th bombing, members of the Armenian Secret Army for the Liberation of Armenia (ASALA) had planted the device. Three ASALA members were arrested later the same day after a four-month long investigation by the FBI and LAPD.

All three attackers, including another from France, were convicted of creating an explosive device with intention to cause mass harm.


In Tampa Bay, Florida, 15-year-old Lisa Davis was shot dead at the now-defunct Rabbit’s Foot Bar, after a bullet entered her head through the cheekbone.

The bar was known to have a rough reputation and was nicknamed the Buckets of Blood Bar due to the amount of violence there.

The case immediately went cold for 23 years until May 2006 when a cold case unit arrested 47-year-old Rosemary Davis, who wasn’t related to Lisa.

They discovered that Rosemary had been in an argument at the bar with another woman, pulled a gun and fired into the group the woman was with.

The bullet struck Lisa, who was with friends nearby. The gun was given to her by a man who told her to fire into the air to scare them but instead Rosemary shot into the group.

Rosemary was charged with second-degree murder.
