Wynborne Cunningham, 26

Wynborne Cunningham, a 26-year-old black man, was found stabbed to death Sunday, Dec. 10, in the 2000 block of South Arlington Street in Arlington Heights, according to Los Angeles County coroner’s records.

On Wednesday, Dec. 6 between 7 and 10 p.m., Cunningham got into an argument with a cousin who had come to visit, which resulted in a stabbing inside the victim's apartment, said Los Angeles Police Lt. John Radtke.

The suspect, later identified as Ethan Webber, a 24-year-old black man, then jumped from a window in the second-floor apartment and ran away, investigators said. 

On Dec. 10, an apartment manager discovered Cunningham’s body, police said. Authorities were called, and Cunningham was pronounced dead at the scene at 1:57 p.m., according to coroner’s records.

Cunningham was an Air Force veteran and had been living in Los Angeles for a short period of time, police said. His cousin had come to visit him from out of state, Radtke said.

Webber has pleaded not guilty to one count of murder with the allegation that he used a knife as a deadly weapon, according to the Los Angeles County district attorney’s office.

Webber is due back in court Feb. 1.
