A 19-year-old man killed his father and assaulted his mother at their home in Woodbridge, Virginia, early Monday, police say.
Someone called police about the suspect, Juan Pina-Ortiz, destroying things inside the home on Shannon Court and possibly being under the influence of an unknown narcotic, Prince William County police said.
When officers got to the home just before 1:30 a.m., they saw Pina-Ortiz, who was nude, actively assaulting his father, police said.
The suspect ignored the officers' commands and continued to assault his father, according to police. Then, he briefly went into a different part of the home.

Police said Pina-Ortiz suffered minor injuries and was treated at a hospital.
His father, 51-year-old Juan Pina-Recendiz, died at the home from blunt force trauma he suffered in the assault, police said.
