Authorities say one man has been killed and two people have been injured in a Springfield attack.

Police said in a news release that 19-year-old David Shockley, of Springfield, was found outside a home Thursday with injuries consistent with a gunshot wound. He was transported to a hospital, where he later died.

Police say two others also were taken to a hospital with injuries that weren't considered life threatening. One of the people had been shot and the other had been struck in the head with a blunt object.

The Springfield News-Leader reports that Lt. Tad Peters says officers were searching for multiple suspects. He says it is likely that the people at the home knew the suspects.
