(CHESTERFIELD TOWNSHIP) -- A 23-year-old Tuscola County man is on the run after police say he tied up his ex-girlfriend and partially put her inside a Christmas tree bag. Police went to check on the 20-year-old Chesterfield Township woman's safety about 1 a.m. Friday after her family called from Florida. Officers heard her scream for help when they called her name. The ex-boyfriend, Jonathan Elbers of Reese, broke free from the officers during a struggle and fled from the house. The victim told police that Elbers was upset after they recently broke up. She said he tied her with electrical cord and choked her. Police say she struck him in the head with a porcelain statue. A rifle and duct tape was found in the man's truck which was parked nearby. Anyone with information on Elber's whereabouts is asked to call the Chesterfield Township Police Department at 586-949-2322 or Crime Stoppers at 1-800-SPEAK-UP.
