4 Mansfield Police SWAT officers were involved in Saturday's fatal shooting

Mansfield Police Chief Jason Bammann noted in a news release Tuesday, among other things, that Oswalt released two children during the three-hour negotiations.

How deadly the shooting ended

When officers tried to make contact with a man they identified as Oswalt, he closed the door and barricaded himself and two children inside, police said. According to Bammann, a woman managed to get back into the apartment through the back door. Officers established communication with Oswalt. Hostage negotiators and the Richland County ASORT team arrived to begin negotiations.

A short time later, the woman was able to escape through the back door, where SWAT operator Sgt. Shane Gess, Sgt. Michael Haines, Sgt. Joseph Gladden and officer Paul Webb were moved into position, Bammann said.
