Boy accused of killing 13-year-old girl found in her bedroom

Authorities are trying to determine the relationship between a teen boy and a 13-year-old girl he's accused of killing after her body was found in the Northern California home where they both lived.

Police say the girl's mother found her dead Tuesday in the city of Rocklin. They say it appears the victim died of head injuries.

The 14-year-old boy fled the home, and authorities tracked him down after about 40 minutes and arrested him.

Capt. Lon Milka said Wednesday that police haven't yet interviewed the victim's parents to determine the teens' relationship because they are too distraught.

Rocklin is an affluent bedroom community about 25 miles northeast of Sacramento. It's the city's first homicide since 2013 and the fourth since 2003.
