(WHAS11) -- A Western High School student is locked-up in the Jefferson County Youth Detention Center, charged with murder. He's accused of killing 17-year-old Darnishia Peoples.
The boy's father is convinced it was suicide.
"Darnishia a sweet girl, loved being around her, special. Can't believe all this happened," said the boy's father, John Robinson.
The teenage girl was stabbed to death in Shively around 9:30 Saturday night at the 2200 block of Peaslee Road.
Her 17-year-old ex-boyfriend, a Western High School senior, is the prime suspect. Robinson says his son told him it was suicide.
"He just said he tried to save her. That was it, he tried to save her," said Robinson.
Robinson rushed home from a birthday after his daughter called, sounding freaked out. He found Peoples in a pool of blood by the refrigerator and called police. Robinson trusts his son's story.
"I just told him to be strong. He said he didn't do it, I believe him and told him I'm standing behind him," said Robinson.
The Jefferson County Coroner's Office says Peoples died of sharp force wounds and ruled the death a homicide.
Shively's police chief says they don't believe the stabbing was self-inflicted and that investigators are gathering more evidence and talking to family members.
Robinson says he has a good son who loved to cook and wanted to be a boxer.
"A lot of grieving and questions. Just up in the air," said Robinson.
Peoples' family was not available for comment.
