Cedar Rapids Police Chief Wayne Jerman says he's concerned and disturbed by two weekend shooting incidents that left two people dead and one person injured.

"It's definitely disturbing," Jerman said Sunday afternoon during a news briefing with reporters. "It needs to stop."

The first incident happened Friday evening when police responded to a home at 1424 Bever Ave. SE around 5:45. Once on scene officers found Senquez Jackson, 15, suffering from a gunshot wound. Jackson was taken to a local hospital where he was pronounced dead Saturday night.

Jerman said the incident is being treated as a "death investigation" at this time and there have been no arrests. Jerman said investigators have interviewed the person believed to be the shooter.

A second shooting happened Saturday night just before 9:45 when officers responded to a report of multiple gunshots in the 1100 block of Maplewood Dr. NE. Authorities say Brandon Johnson, 21, was pronounced dead at the scene. A second person, a 16-year-old boy, was taken to the hospital with what authorities described as a non-life threatening wound.

"It's very upsetting, regardless of a person's age," said Jerman. "The loss of life is tremendously tragic."

Police said the Maplewood Dr. NE shooting appears to be the result of a dispute between families involving juveniles, young adults and parents. Police are looking for Kenyauta Keith, 16, who is described as a person of interest in the case.

Jerman said he wants to see parents challenge their sons and daughters to limit gun violence in the community. Jerman said his department is "unbelievably committed" to ending violence before it progresses.

Jerman said the weekend incidents are not related.
