LOUISVILLE, Ky. (WHAS11) – One man is dead and another is seriously injured in Pleasure Ridge Park near Terry and Greenwood Rd.

Police suspect Barry Barger, who has been arrested, tried to take his own life after shooting and killing his girlfriend's son.

Family members described trouble between the victim, who was in his 20s, and his mother's boyfriend.

They said the men argued last night and the mother was not home when the shooting took place this morning.

The suspect was taken to the hospital with what investigators described as serious injuries.

"I work third shift. I've been asleep. My mother runs upstairs hysterical beating my door down and just says that somebody shot somebody in a situation and I knew who it was due to a fight that happened last night. So I had my friend bring me over and this is what it is,” Donna Hale, the victim’s aunt, said.

The family also told us that the victim’s pregnant girlfriend was inside the home at the time of the killing.

We expect detectives to release the identities of those involved sometime this evening.
