A Rock Island man on Friday admitted that he acted in the heat of passion when he fatally shot 19-year-old Louis K. Woodson Jr. in September 2015.

Juwan Attron Johnson, 19, initially faced a charge of first-degree murder but pleaded guilty to voluntary manslaughter and intimidation with a dangerous weapon with intent during a 30-minute hearing in Scott County District Court.

Both charges are Class C felonies, each punishable by up to 10 years in prison.

Prosecutors are seeking an enhancement on the intimidation charge, which would require Johnson to serve at least five years in prison before he is eligible for parole. 

The sentences will run back-to-back, according to the plea agreement. Johnson also will be required to pay $150,000 in victim restitution. He will be sentenced April 27.

About 1:24 a.m. Sept. 2, 2015, officers responded to the Brady Mart, 3107 Brady St. for a report of a shooting, according to police.

Johnson was in possession of a 9mm handgun and waited in the parking lot for three people to leave the store, police said.

Three people ran from the business, and two of them got into a waiting vehicle. Johnson fired several rounds into the vehicle and struck Woodson, who was in the back seat, according to police.

Johnson was identified by witnesses at the scene, according to police.

Woodson, of Quincy, Illinois, suffered two gunshot wounds and was pronounced dead at Genesis Medical Center-East Rusholme Street, Davenport.

During the hearing, Johnson admitted that he acted in a sudden or irresistible passion because of serious provocation. 

In November 2012, Johnson was adjudicated as a delinquent juvenile on a felony charge of mob action in Rock Island County.

In February 2015, Johnson pleaded guilty in Scott County to being a felon in possession of a firearm and was sentenced to two years of probation and a suspended five-year prison term.

A petition to revoke his bond was filed Sept. 10, 2015, and a bench warrant was issued for him the following day. A revocation hearing is scheduled for April 20.
