The assault occurred around 2:15 a.m. in the 100 block of Barranca Lane, where San Mateo County sheriff’s deputies found an 18-year-old with severe injuries to his face and head.
Investigators said a girl was in her room when an acquaintance jumped through her open window, screaming for help after running from someone, according to the sheriff's office.
