FEDERAL WAY, Wash. -- Neighbors of a man accused of strangling a 75-year-old woman in Federal Way said he has a fierce temper and often erupted in rage outside his apartment.

Joseph Njonge, 24, is accused of killing Jane Britt, who police said met him at the Garden Terrace Nursing home where her husband is a resident.

David Hicks said he saw Njonge get angry at least twice.

"There was one incident where he pulled in with his girlfriend and they ran up on the curb over there and he just left his car there. (He) got out and left her in the passenger (seat) and he kind of walked off. And then there was another time … I happened to look out and saw him whip his cell phone at her," Hicks said.

Hicks said he saw an eviction notice on Njonge's apartment door.

Meanwhile, newly unsealed court documents revealed that a piece of plastic was likely used to strangle Britt.

The plastic appears to match the nursing home's garbage can liners, according to a search warrant served at the suspect's apartment.
