A grisly discovery in northern California on Sunday led authorities to an elderly woman's suspected killer when cops found a man covered in blood lying in the middle of a street, according to officials.

The Roseville Police Department said in a Facebook post that officers initially received a report about a "subject lying in the street" and responded.

"Upon arrival officers contacted a conscious male covered in blood," police said.

As officers began to investigate, they found an elderly woman dead at a nearby home who was "associated with the male."
