WEST HOLLYWOOD (CBSLA) — Authorities Monday were investigating the death of a man who apparently fell or was pushed from an apartment window in West Hollywood.

Deputies responding to an initial report of a stabbing found the unidentified man dead just before 7 a.m. on the 1100 block of Hacienda Place, sheriff’s officials said.

Detectives were working to determine whether the fall was intentional or accidental.

“There is some signs of some type of struggle or some type of scuffle that may have occurred inside there,” said LA County Sheriff’s Dept. Lt. Derrick Alfred.

A screen on the window from which the victim fell was apparently torn, CBS2’s Greg Mills reported.

“We heard a loud thump. 9:30,” said Michael, who lives in the building and is an acquaintance of the two men who live in the apartment. He said it’s two men in their 20s who own a dog.

He didn’t investigate the thump he heard Sunday night but he did see the body Monday and said he thinks it’s a man much older than someone in his 20s.

Lisa Dinsmore was walking her dog and stood across the street around 7 a.m.

“I saw them escort a gentleman out, a tall and slender gentleman, in handcuffs and take him into one of the eight police cars at the top of the hill and drove off,” said Dinsmore.

The sheriff’s department told Mills that man was one of the roommates. He was taken and questioned and brought back to pick up his dog and released.

An autopsy was pending to determine the man’s cause of death.

Anyone with information on the case was urged to call the Sheriff’s Homicide Bureau at (323) 890-5500.
