A second person has been arrested in the shooting deaths of two men sitting in a vehicle last week in north Minneapolis, authorities said Sunday.

The newest person arrested is 30 years old and from Minneapolis. He was arrested Saturday by homicide investigators with the help of his family members, said police spokesman John Elder. He has yet to be charged.

The other suspect, Brian Deshawn Morse, 21, of Chicago, was charged with two counts of second-degree murder in Wednesday’s late-morning gunfire in the 4500 block of Penn Avenue N.

Police have said the incident does not appear to be random.

One victim, 47-year-old Odell M. Frazier, moved his family to the Twin Cities from Chicago’s South Side five or six years ago. The second victim, 56-year-old Eddie J. Pelmore, of Minneapolis, was said to be a friend of Frazier’s.

Family members said Frazier was getting his 6-year-old daughter ready for school when he walked outside to talk to a friend. They climbed inside an SUV outside Frazier’s home, where he lived with his wife and several of his nine children.

Police said two men approached the vehicle and at least one of them fired several times, striking both victims.

Both men were pronounced dead at the scene, marking the city’s fifth and sixth homicides of the year.

Morse initially denied involvement in the shooting but later said he was there while another man shot both victims, according to the charges. Blood on Morse’s pants was from the victims, the complaint continued.
