Minneapolis police are investigating a shooting early Tuesday in the Hawthorne neighborhood that seriously injured a man who was holding an infant in his arms.

The infant was not wounded, according to department spokeswoman Sgt. Darcy Horn. Police did not disclose the child’s age.

Officers were summoned just after 4 a.m. to a house in the 400 block of 24th Avenue N. after the area’s ShotSpotter network detected two gunshots in the rear of the property, according to Horn and emergency radio transmissions posted online.

En route, they learned that someone had been shot, Horn said. When they arrived, they found the victim suffering from a gunshot wound. He was transported to North Memorial Medical Center, where he was listed in serious condition, she said.

The investigation continued throughout the day, but no suspects were in custody as of Tuesday evening.
