(KMOV) -- Police say they now believe that the two victims in a deadly shooting on Tuesday at a funeral home were killed following an argument that began while they were attending a funeral.
They say those involved in the argument went outside where the shootings then took place.
It happened at the Reliable Funeral Home in the 3900 block of Washington Avenue during services for a homicide victim.
A subsequent police investigation revealed that the victims knew one another and that they began shooting at one another.
Jason Finney, 31, and Trevlan Glass, 31, were shot multiple times. They were both taken to area hospitals where they were pronounced dead.
A 35-year-old black male was also shot multiple times. He was taken to an area hospital and listed in critical condition.
Witnesses at the scene reported a fourth person was shot and ran from the scene prior to police arriving. That person has not been found. It is unclear if this individual is a suspect and a victim or simply a victim.
It appears all of the shooting took place outside of the funeral home, though the investigation is still ongoing. Police are still interviewing witnesses to determine if there are additional suspects or victims.
The funeral service was being held for David Davis, 27, of University City. He was shot multiple times in the head and chest around 10:40 a.m. on November 19 in an alleyway in the 4700 block of Sacramento in north St. Louis.
Witnesses say they heard two men arguing in the alley just before they heard gunshots. No one has been arrested in connection with Davis' death.
