A man was shot to death by his stepfather when he threatened his mother with a knife in Encinitas, authorities said Friday.

The shooting occurred in the early morning on Monday at a home in the 1200 block of Greenlake Drive, San Diego County sheriff’s Lt. Michael Blevins said.

Medics took Robert Dean, 59, to a hospital where he was pronounced dead, Blevins said.

Barbara Miller, 80, called the sheriff’s department to report being threatened by her adult son, Blevins said.

The stepfather, identified as William Miller, 74, “armed himself with a gun and shot the son,” Blevins said.

Barbara Miller did not suffer any injuries. Detectives questioned William Miller, Blevins said.
