Patrick Mullinnex was found with a gunshot wound to the chest on August 3 in a Pleasant Street apartment. The 38-year-old was also a suspect in a kidnapping and assault in Springfield, Vermont in July. It’s unclear if the two incidents are related.
Cardona, 28, of Springfield, Mass., was considered armed and dangerous after the shooting. An arrest warrant was issued before he turned himself in.
He will remain in police custody without bail until his arraignment on Tuesday. He was charged with second-degree murder.
