ROCKFORD, Ill. (WTVO) – UPDATED: Two men were killed and four people were injured in three shootings in Rockford’s West side on Tuesday.

A 28-year-old man was killed after being shot in a home on Jonathan Avenue around 5:30 p.m., according to police. Security video released later showed three masked individuals approach the front door and open fire on the occupants.

Officers rushed to Sherman Ave. around 7:45 p.m. for reports of a shooting where police say Tyree Isom, 19, shot a 16-year-old in an apparent altercation over a drug deal.

A 16-year-old victim was taken to the hospital with gunshot wounds, police said. He was shot in the thigh and is expected to survive.

Emergency crews were also called to the 400 block of Independence Ave. around 8:30 p.m. for several additional shooting victims.

A 38-year-old man was taken to the hospital where he later died.

A 36-year-old man suffered serious, life threatening injuries, police said.

Two other men, 30 and 35, had serious injuries.

Police said they do not believe the Jonathan and Independence Avenue shootings are related, but Rockford Police Chief Carla Redd said the shootings appear to be targeted and not random, and did not believe there was a threat to public safety.

“I can’t say they’re gang related, but the individuals that are involved, the individuals are known to one another,” Redd said.
