The suspect in a deadly Christmas Eve shooting in Oxford Township has a history of gun crimes and was recently released from prison despite picking up another weapons conviction while behind bars, the Free Press has found.

Records indicate that the man who authorities say opened fire on Christmas Eve, killing one and injuring two, was just discharged from prison in July.

There appears to be no connection between the shooter, the victim, or the location where it happened, sheriff Michael Bouchard told FOX 2 on Thursday. Instead, he called the random shooting an “incredibly violent rampage.
