Vivian Wolff was discovered when Garden Grove police were called at 9:43 p.m. to a condo complex known as the Flower Tree, in the 14000 block of Flower Street, just off Westminster Boulevard.

Police did not immediately release her name or disclose who initially called 911.

Garden Grove police Lt. Carl Whitney told CBS2 Wednesday the woman was renting a room in the condo along with her 28-year-old son. Jonathan Michael Warner is at large and is considered a person of interest in the case. The two were last seen alive on Saturday.

There was no word on a motive.

Neighbors told CBS2 that the condo was owned by a widow in her 50s who had been living there alone until recently, when the victim appeared to have moved in as a tenant. One man told CBS2 he saw the widow walking alone just hours before police arrived Tuesday night.

“Yesterday, about 7:30…I was working in my garage and saw her,” neighbor Armando Martinez told CBS2 Wednesday.

Detectives at the scene were seen taping off a black Kia Sportage parked in front of the complex.
