Officials didn’t release much in the way of details but neighbors told CBS2/KCAL9 News that the victim and the man who was detained are neighbors and have been getting into quarrels for years.

Residents in this condo complex also say police were called to the condo unit Wednesday, when “the victim verbally attacked the wife of the suspect, calling her lots of very, very bad names, and calling her children names,” according to neighbor Shanna Foster, who says she’s friends with the suspect’s family. “There have been physical altercations. [The victim] has attacked the suspect with a baseball bat, as well.”

Owens said, “One’s going to prison, maybe for the rest of his life, and the other’s going to the graveyard.”
