CHESTERFIELD TWP. (WWJ) – Chesterfield Township police are searching for a man who allegedly threatened to kill his ex-girlfriend — and was in the process of carrying out that threat when they showed up.

Police said they were called to the woman’s home by her parents, who were in Florida at the time, and concerned about their daughter’s welfare.

When they arrived at the home, police say they heard the 20-year-old victim yelling for help from the basement, and saw the suspect, 23-year-old Jonathan Elbers, bleeding heavily from a head wound.

Elbers refused to comply with officers’ commands and a struggle ensued, with Elbers ultimately breaking free and fleeing on foot.

The young woman told police that Elbers was in the process of tying her up and forcing her into a large Christmas tree bag when officers arrived.  She said Elbers choked her and told her he planned to put her into the back of his truck and shoot her in the head.

She explained that when Elbers heard police arrived he paused, and she took that opportunity to strike him in the head with a porcelain statue.

A K-9 searched turned up no sign of him and he remained on the run at 2:30 p.m. Friday.

Officers later found Ebers’ truck parked near the victim’s home — with a rifle and duct tape on the front seat.

Elbers is around 5 feet, 10 inches tall and 155 pounds. He was wearing a dark, long-sleeve  T-shirt, cargo-style jeans and work boots.   His hair is  described as longer and “shaggy” as compared to the photo above.  He will likely have a noticeable head wound.

He’s wanted on multiple felony charges including assault with intent to murder, unlawful imprisonment, assaulting an officer causing injury, and home invasion.

Police said Elbers should be considered extremely dangerous.
