A man was killed and five others were wounded in five separate shootings on the city's north and south sides, police said Wednesday.

The five shootings occurred within two hours Tuesday night, including the fatal shooting of a 48-year-old man shortly after 11 p.m. in the 500 block of W. Concordia Ave.

The man died at the scene, and there were no suspects in custody, police said Wednesday.

The man's killing occurred two days after a 29-year-old woman was shot to death while driving past a north side street corner where a shooter opened fire on a group of people.

In the four other shootings Tuesday night, according to a Milwaukee Police Department news release:

■ A 55-year-old man was wounded while sitting in his home in the 1400 block of W. Greenfield Ave. about 9:15 p.m.

■ A 19-year-old man was shot while getting into his car in the 3700 block of N. 27th St. shortly after 9:30 p.m. He drove himself to a hospital for treatment.

■ An 18-year-old and a 17-year-old were wounded in a shooting that police think was related to drugs around 9:45 p.m. in the 3500 block of N. 55th St. A suspect was in custody, police said Wednesday.

■ A 51-year-old man was wounded in his home in the 1500 block of S. Muskego Ave. around 10:45 p.m.

The injuries of those wounded Tuesday night are not life-threatening, police said.

On Monday, Fredricka S. Hodges, 29, was fatally shot while stopped at N. 24th and W. Center streets.

According to police, an 18-year-old man was wounded in the incident, in which someone opened fire on a group of people standing on a street corner.

There is no indication that Hodges was among those targeted by the gunfire, police said.

Milwaukee police have recorded 13 homicides in the city since Jan. 1.

Four other people have been killed in 2014 in shootings that have been ruled self-defense, according to police.
