WICHITA, Kan. (AP) — Authorities in Sedgwick County are asking for the public’s help in finding the person they say stabbed a Wichita man whose body was found in a sport utility vehicle on Christmas Eve.

The Wichita Eagle reports that a Park City police officer found 42-year-old Moises Arias-Aranda dead in a maroon, 1994 Ford Explorer shortly before 7 p.m. Dec. 24.

Sheriff’s Capt. Greg Pollock says someone in the Wichita-Sedgwick County area knows what happened to Aranda, and that that person needs to come forward to investigators.
