When police arrested a man with an active warrant during a traffic stop, they found evidence in his car that he was preparing to shoot heroin.

Jacob A. Christian, 24, New London, is charged in Waupaca County with possession of narcotics and possession of drug paraphernalia.

On Nov. 2, Winnebago County Circuit Court issued a warrant for Christian after he failed to make a scheduled court appearance on felony narcotics charges.

On Thursday, Dec. 3, New London Police Officer Brody Erickson was in a car outside America’s Best Value Inn watching the hotel’s parking lot. He had been informed that Christian was staying there and would be leaving in a black Pontiac Grand Am.

When Erickson saw Christian drive away, he followed him and pulled him over a few blocks later.

Officer Todd Sarazin arrived at the scene to assist.

Sarazin approached the vehicle and told Christian to get out.

According to the criminal complaint, Sarazin noticed Christian’s hands were shaking. He also reported seeing a needle sticking into the driver’s seat, next to Christian’s right leg.

After Christian left the vehicle, Sarazin found a metal cap with a small, grayish granule in the center of a dark liquid on the driver’s seat. There was also a foil wrapper on the seat with another granule in it, the complaint says.

Police reported finding another metal cap and syringe in Christian’s jacket pocket.

Christian told investigators he was using only half a bindle of heroin at a time, the complaint says.

He is being held in Winnebago County jail on a $500 cash bond.
