The 60-year-old Los Angeles man fatally shot his wife, who had dementia, an then went to a convalescent home and shot and killed his sister.

Lance Holger Anderson of suburban Santa Clarita surrendered at the nursing home and was booked on suspicion of murder, shocking neighbors who described him as a chatty, friendly man who doted on his frail wife.

“He treated her like she was a jewel … because she was so fragile,” Gale Madrigal said.

Anderson walked into the Country Villa Sheraton nursing facility in the North Hills area of Los Angeles shortly before 9:30 a.m. and shot his sister Lisa Nave in the head, police said.

Nave, 58, had been at the home for about five years and was in a vegetative state or coma, police said.
