A 14-year-old boy was arrested Wednesday on suspicion of stabbing his teen sister to death in Southern California, police said.
Officers responded to a 911 call of a female victim not breathing at a residence in the 300 block of Andover Drive at 5:07 p.m in Claremont. Emergency crews took lifesaving measures, but the 15-year-old girl succumbed to her injuries, Claremont police said.
Police said the 14-year-old boy was taken into custody after he was spotted walking away from the home. No one else was home when the stabbing occurred, police said.

One parent was at work, the other was running errands, according to the Los Angeles Times. NBC4 attempted to contact family members, but did not receive a response as of Thursday morning.
Neighbors were stunned to hear of the crime and said they recently saw the pair playing basketball in their yard.
"I guess it could happen anywhere but these people's lives just completely changed this evening," said Grace Felschundneff, a neighbor. "I just can't imagine what's going on with the family. I can't imagine."
Officials said there hasn't been a homicide in Claremont since Oct. 2009.
