Protesters demonstrated outside the home of Deputy Miguel Vega in Covina, demanding he face prosecution for the killing of 18-year-old Andres Guardado near Gardena in June.

About a hundred protesters started out pretty peacefully, marching on the sidewalk outside the Covina home.

The 18-year-old Guardado was working as a security guard in June when deputies from the Compton station say he ran away when they tried to stop him.

They claim he had a weapon, which they insist they recovered at the scene. His family counters that he was shot five times in the back, and did not own a gun.

There have been numerous protests, as the investigation continues, but it’s only recently that people have been gathering outside the home of the deputy who fired at Guardado.

Covina police showed up when someone used chalk to tag the front walkway of the small house.

Things quickly turned ugly, and by the end of the night, three people were in custody.

Protesters say they were peaceful, officers say they were trespassing.

There are plans for further demonstrations at the house.

The protest began around 4 p.m., authorities said.
