A man is in jail after allegedly shooting another man in front of his grandchildren Sunday.

According to Streck, a man went to a home and asked for another man who was not there. Barnett’s grandsons, who are 20 and 15 years old, couldn’t calm the man down so he went over to de-escalate the situation. The man then pulled out a gun and shot Barnett in front of his two grandsons and some neighbors.

The man fled the scene but deputies were able to track him down a couple of blocks away in a wooded area and arrest him, Streck said.

The suspect was booked in jail on suspicion of murder. Official charges will be determined by the Montgomery County Prosecutor’s Office as the case progresses.
