A police dragnet late Thursday night, in which Ardmore Police Chief Ken Grace said "we are going to scour every street in Ardmore," slowly and deliberately tightened the noose around an 18-year-old trigger man believed to have been involved in four shootings in less than 24 hours, including one murder.

The all-out manhunt for Henry "Lil Henry" Jackson began about 6:30 p.m. when he shot two federal agents assisting APD investigators, and riddled a pair of law enforcement vehicles with bullets. Grace identified the agents as members of Alcohol Tobacco and Firearms. One of the agents sustained only minor injuries and was treated at the scene in the 900 block of K Street NE. Grace said the other agent wasn't as lucky. He was hospitalized with gunshot wounds to the forehead and leg.

No Ardmore officers were injured in the encounter with the man described as "armed and very dangerous."

APD officers had ramped up the search for Jackson in the late afternoon after obtaining information he was behind the wheel of a stolen 1998 silver Ford Taurus. Grace said Det. Billy Turner and the federal agents spotted the 18-year-old shooter driving the car in the northeast side neighborhood.

By 8 p.m., Grace had amassed an army of law enforcement officers determined to hunt down Jackson.

In addition to Ardmore police, Carter County Sheriff's deputies and other area law enforcement agencies joined the search.

At the same time the manhunt for Jackson progressed in Ardmore, the Johnston County Sheriff's Department was investigating a murder believed to have been committed by Jackson. Sheriff Jon Smith confirmed the shooting death of a victim, but declined to release a name pending the notification of relatives.

He said while the investigation remained ongoing, preliminary evidence linked Jackson to the murder.

"From a description obtained from witness, at this time it appears it was Jackson," Smith said.
