A man is dead and a second was in the hospital Monday after they were shot while sitting in a vehicle in St. Paul's Payne-Phalen neighborhood, police said.

The shooting happened shortly after 9 p.m. Sunday near the intersection of Payne Avenue and Jessamine Avenue E.

One person was arrested that evening for allegedly aiding an offender to avoid arrest. No charges had been filed against that suspect or anyone else as of Monday afternoon.

Officers were on patrol in the area when shots were fired, and they immediately responded. Paramedics took both victims to Regions Hospital, where one of the men died and the other was being treated for his injuries, police said.

Police have not released the names of the victims.

Investigators with the department's homicide unit were on the scene looking for evidence. They also were looking for witnesses or anybody who may have information on what led to the shooting.

Police on Monday also announced that a 22-year-old man who was shot on Dec. 2 died Sunday. Authorities have not officially identified the victim, but a police report listed him as Mohamed Ali Mohamoud of St. Paul.

Mohamoud was shot about 10:20 p.m. in the 1200 block of Marshall Avenue. He was taken to Regions Hospital in a private vehicle with an apparent gunshot wound to the head.

Mohamoud was treated and remained in intensive care until he died. No arrests have been made, and the investigation is ongoing.
