RIVERSIDE, Calif. (AP) — Authorities say a Virginia sheriff’s deputy who they believe traveled to California to kill three family members of a 15-year-old girl he tried to sexually extort online killed himself with a government-issued firearm. Police say 28-year-old Austin Lee Edwards drove across the country and on Nov. 25 killed the girl’s mother and grandparents and set fire to their home in Riverside, about 50 miles east of Los Angeles. That same day, Edwards died by suicide during a shootout with San Bernardino sheriff’s deputies. The girl was rescued. Sheriff’s spokeswoman Gloria Huerta says Edward used his service pistol to kill himself. The Riverside Police Department, which is investigating the family members’ deaths, hasn’t said how they were killed.
