Del City man arrested for killing 15-year-old grandson

Del City police say detectives have arrested a man for killing a 15-year-old relative.

Police say 56-year-old Lochinvar Caldwell was booked on a first degree murder complaint.

According to police, officers went to a home Friday night after someone reported a fight between Caldwell and a neighbor. Caldwell wasn't clothed and "appeared delusional," according to a report.

A 17-year-old female was also at the home. She told police that Caldwell shot and killed her 15-year-old brother inside the home, then forced her to say with him.

Investigators found 15-year-old Jaquelin Caldwell inside a bedroom, dead.

Lochinvar Caldwell was then arrested and taken to a nearby hospital to be checked out. He was then booked in the Oklahoma County Jail.

The case is still under investigation, police said.
