Angela Jaramillo was 16 when she left home in Dallas, Texas, late on January 23, 2010, to go to a party at a boy’s house. That night she texted her mother asking to stay with a friend. The following morning she didn’t respond to her mother and never arrived at the friend’s house as planned. The host said Angela left the party about 2:00 a.m. and was not seen again.

Her disappearance was first treated as a runaway case. Over time investigators began to suspect foul play after Angela’s cell phone was found in a local park and there were indications she might have been injured. She had no history of running away and her bank account showed no activity after she vanished. Several reported sightings in the Dallas area were never confirmed and the case remains unsolved.

Anyone who knew Angela, was at the party that night, or has information about her whereabouts is asked to come forward.
