A man who was sought as a “person of interest” in the “suspicious” death of a woman at a residence in Whittier has been arrested on suspicion of murder, police said Wednesday.
Rafael Castillo, 56, was taken into custody in Reseda by Whittier officers, according to a post on the Police Department’s Facebook page.
He was questioned following a traffic stop and subsequently arrested, Sgt. Dominic Iraldo said.
He was booked at the Whittier Police Department Jail and is being held on $1 million.
Castillo is suspected in the homicide of 54-year-old Sandra Polanco, whose body was discovered in the 11700 block of Floral Avenue around 7:30 a.m. Tuesday, according to authorities.
Firefighters had responded to an assault or abuse call at the residence, where they found the deceased woman.
A cause of death was not immediately released.
Neighbors told KTLA Castillo and Polanco were a couple who lived together.
Castillo “seemed like a nice guy,” neighbor Guillermo Cedno said.
“He introduced himself when I first moved in,” Cedno said. “He said, ‘I live right here in the front. If you ever need anything — I’m here.'”
Another neighbor who was friends with Polanco described her as a “very caring,” “very nice” woman who was “really funny.”
Police have not elaborated on the relationship, confirming only that the pair knew one another.
Castillo is due in court Thursday.
