Incident

Sergeant O'Donnell was shot and killed as he and another trooper escorted a prisoner back to New Jersey. The 30-year-old prisoner, a former mental patient wanted in Newark for murdering his wife with an axe, had been arrested in Pennsylvania and had agreed to turn himself in to New Jersey authorities. Sergeant O'Donnell and another trooper met the suspect on the Pennsylvania side of a railroad bridge and began to walk the suspect back across the river. As they got to the midpoint of the bridge the suspect attempted to jump over the railing, but was stopped by Sergeant O'Donnell. During the ensuing struggle the suspect was able to grab Sergeant O'Donnell's revolver and shot him twice in the abdomen, causing fatal wounds. He also shot the other trooper who later recovered from his wounds. He was captured later that night in a wooded area near the scene. On September 19, 1945, he was convicted of Sergeant O'Donnell's murder and sentenced to life. Four months later he was declared insane and the trial for his wife's murder was put off indefinitely. He died in prison December 18, 1962. Sergeant O'Donnell had served with the agency for 17 years.
