KSDK - Police say 20-year-old John P. McCord beat one man to death and critically injured a woman in a home in the 3900 block of Eichelberger.
The body of 20-year-old Naeoky Guzman was found Sunday morning. He died of blunt-force trauma to the head. A 19-year-old woman was also critically injured. They were reportedly hit with a hammer.
McCord is charged with first degree murder, assault, and armed criminal action.
Manuela Soto, the victim's cousin, said, "He [Guzman] was always very funny. He always made us laugh. He saw life, I mean, he didn't see anything evil about it."
Naeoky Guzman was a 2004 graduate of Lindberg High School in South County.
Police had not released a possible motive Thursday.
