BAY ST. LOUIS, Miss. (AP) — Authorities say a man killed his mother, stepfather and girlfriend at their Mississippi home before he climbed a cellphone tower and plunged about 300 feet to his death.

The triple homicide occurred Saturday in Bay St. Louis, which is along the Gulf Coast.

No motive has been disclosed in the killings.

Authorities identified the victims in the Bay St. Louis slayings as Wilton Bernard Jr., his wife, Jeanie Bernard, and Kathleen Deese.

The suspect, Anthony Garrett, died later Saturday night as authorities tried to talk him down from a tower in nearby Waveland.
