Two people, including a 4-day-old boy, were wounded by gunfire on Detroit’s east side Wednesday night, the latest young victim injured by gunfire since April.

The infant and his mother, a 24-year-old woman, were inside a home in the 16100 block of Maddelein about 10:20 p.m. when “unknown suspects shot up the home,” said Officer Jennifer Moreno, a spokeswoman for the Detroit Police Department.

The boy was grazed by the shot, said Dontae Freeman, social media manager for the Detroit Police Department. Moreno confirmed earlier the boy was hit in the head.

The boy and his mother were both in temporary serious condition at last report. Medics transported the two to the hospital, where police met them and started the investigation.

Police believe that the suspect, described as a 20-year-old black woman, is known to the victim, and that the two had been having a disagreement before the suspect's car was spotted in front of the home, opening fire.

The shooting was the latest in a violent 24-hour span that saw a string of incidents across the Motor City.

In a seven-hour span starting late Tuesday, police reported seven people shot in six instances. One of the victims died.

Later Wednesday, a man described as acting erratically at a hotel was shot by police after allegedly opening fire on officers with a 9 mm gun.

The gunfire on Maddelein also came about two weeks after a 7-year-old girl was shot in the face while sleeping in her grandmother’s arms.

On April 1, a 9-year-old boy was shot in the head after witnesses allege someone exited a silver Dodge Magnum and opened fire with an AK-47. The child survived but lost his eye. The incident prompted dozens of people to march in a peace walk.
