A suspect was arrested early Wednesday in connection with the fatal shooting of a Columbia Heights man as he sat in his car in south Minneapolis Tuesday afternoon.

The 29-year-old man was arrested about 3:30 a.m., nearly 12 hours after numerous shots were fired into the car at Bloomington Avenue and E. 21st Street, according to police. The victim was Salad Abdi Sahd, 32, the Hennepin County Medical Examiner's Office said Thursday.

The suspect lives in Minneapolis, about 5 miles southeast of where the gunfire rang out in the residential neighborhood. He has yet to be charged. The Star Tribune generally does not identify suspects before they are charged.

Police said a man was seen walking up to the vehicle and opening fire with a handgun before jumping into a waiting car that sped away with another person behind the wheel.

Police spokesman Scott Seroka said his department is not ready to say whether the person in jail is the gunman or the driver.

A video posted to Facebook but since removed showed the victim splayed partly on the ground from the driver's seat as a police officer cut open his shirt and tended to multiple bullet wounds. The officer tried to keep him conscious before medics arrived and took over.

Authorities have not discussed a motive for the shooting.

Dan Wilson, who lives in an apartment that overlooks the crime scene, said it sounded like the suspect "unloaded a full clip" when the gunfire erupted about 4:15 p.m. Tuesday.

"It didn't sound like a firecracker. It sounded like a relatively high-caliber gun," said Wilson, 56, who has lived there for 11 years.

Wilson said he yelled, "Hey, I see you," at the gunman, prompting the suspect to take off.
