An Alsip man faces life in prison after being convicted this week of murdering an FBI informant during a 2006 weapons deal in Dolton, authorities said.

Jerry Henderson, 41, was found guilty of first-degree murder in the shooting death of Timothy Forrest, according to the Cook County State’s Attorney’s office. Henderson is to be sentenced Feb. 26.

Forrest, 41, agreed to buy guns and grenades from Henderson as part of an undercover operation, the state’s attorney’s office said Thursday.

Forrest was given a recording device to wear and $15,000 cash for the operation, the state’s attorney’s office said. The men agreed to meet in Dolton, and authorities saw Henderson enter Forrest’s vehicle, the two have a conversation, and Henderson get out and drive away in his rented vehicle.

FBI agents found Forrest in the car with two gunshot wounds to the head, the state’s attorney’s office said. The $15,000 was missing.

Authorities arrested Henderson the next day at an apartment on Chicago’s South Side, according to the state’s attorney’s office. Authorities recovered a 9 mm handgun that matched the murder weapon and $13,000 cash at the residence.
