Lodi police are seeking a vehicle that may have been occupied by witnesses to a September homicide in which a man was found dead after a house fire.

Police and the Lodi Fire Department responded about 1:45 p.m. Sept. 25 to a structure fire in the 1500 block of West Vine Street. The blaze was too intense for officers to reach anyone inside. After firefighters gained control of the fire, a man was found dead inside the home.

The San Joaquin County Coroner’s Office determined during an autopsy that the man, identified as 53-year-old Alan Karl Gregor Jr., had been stabbed to death before the fire started.

Police are asking the public’s help in finding a 1997 to 2003 red or maroon Ford F-150 pickup truck with a regular cab, long bed and a rolled bed cover. They said the truck’s occupants are thought to be possible witnesses in the case.

Anyone with information regarding the vehicle is asked to call Detective Erika Urrea at 209-333-6885. Callers who wish to remain anonymous may call the Lodi Area Crime Stoppers at 209-369-2746.
