An Orange County woman has been killed while attending a vigil for a man shot to death a day earlier.

The Orange County Register (http://bit.ly/2kvub1j ) says 27-year-old Trisha Verdugo of Orange was hit by a car in a strip-mall parking lot Thursday night.

She and other mourners had gathered at a makeshift shrine outside a vacant Santa Ana store to remember 23-year-old Joseph Garcia. He was found shot to death Wednesday night in the alley behind the store.

Police Cpl. Anthony Bertagna says Verdugo got into an argument with a motorist who hit her with his car, then struck her a second time and drove away.

Police are looking for a dark sedan but have no other details.

Authorities don't know if the two deaths are gang-related.
