St. Louis City and County police share details of 3 linked homicides


ST. LOUIS – Detectives in St. Louis City and County believe they’ve gathered enough evidence and information to link three recent murders in the area. The killings happened three days apart, respectively – on Sept. 13, Sept. 16, and Sept. 19.

Two of the investigations occurred in St. Louis City and the third homicide occurred in St. Louis County jurisdiction involving 16-year-old Marnay Haynes Sept. 13 in the 9900 block of Glen Owen Drive.

“We have been working with the city on the Glen Owen case and we were able to time them together,” St. Louis County Police Lt. Col. Steve Sack said.

“Any loss of life is troubling, but a 16-year-old is even worst. We can’t go into specifics on the victims.”

A woman in her 30s was shot Thursday, Sept. 16, and died at a hospital. She was found lying in the street. Police have not released her name.

The third murder happened Sunday, Sept. 19, in the 1500 block of Mullanphy Street. Casey Ross, 24, was fatally shot at a vacant lot.

Police would say if the suspect involved in all three murders knew the victims or why they were targeted. The suspect is still at large.

Anyone with information on the W. Florissant and Mullanphy murders can contact city homicide detectives at 314-444-5371. Those with information on the Glen Owens killing can contact county investigators at 636-529-8210.

If you have a tip in any of the aforementioned investigations and wish to remain anonymous, you can call CrimeStoppers at 866-371-TIPS.

In a press conference Tuesday morning, St. Louis City and County Police talked about recent crimes and shootings including the four people shot downtown last night. At least one person was killed.

The shooting happened at 20th and St. Charles streets, one block south of Washington Avenue, at about 8:40 p.m.

The victims were attending a candlelight vigil for Demetrise Thomas, 27, who was shot and killed at basically the same location Monday just before 1 a.m.
