SAN DIEGO — A veteran police detective and her 18-year-old daughter were stabbed to death Monday, and her son was arrested on suspicion of murder after he was found sitting next to the teenager's nude body on the sidewalk outside their home, authorities said.
The bodies of Donna Williams, 52, and Briana Williams were discovered by officers who went to the Rancho Penasquitos neighborhood shortly before 1:30 a.m., after neighbors called 911 to report a violent disturbance and a woman screaming for help at a home, police said.
Officers found the teenager's nude body on the sidewalk and her mother in an upstairs bedroom of the two-story home. Williams' son was sitting next to his sister's body and a large kitchen knife was found on the front lawn, the San Diego Union-Tribune reported.
Briana Williams apparently jumped or fell from the balcony, authorities said.
Brian Williams, 24, was arrested on suspicion of first-degree murder and was jailed without bail, according to a San Diego County sheriff's website. It was unclear whether he had obtained a lawyer.
It was unclear what prompted the attack, San Diego Police Department homicide Capt. Jim Collins said at a news conference. He said officers had been called to the house on June 30 because of another disturbance but said the matter had been resolved. He did not provide details.
Donna Williams, a mother of five, was a 31-year veteran of the San Diego Police Department who mainly worked in the child abuse unit. She joined the department in 1980 as a patrolwoman. She joined the child abuse unit in 1989.
"She was known as the cornerstone of the unit," Collins said.
Her husband, Howard Williams, was a former homicide detective with the department who died in 2007.
Briana Williams had just graduated from Mount Carmel High School in San Diego. She played softball in school and had won a full scholarship to attend a San Francisco design college, Collins said.
