Officer David McGuinn was stabbed to death in the maximum-security Maryland House of Correction in Jessup, Maryland, while conducting a nightly prisoner count at 10:00 pm.

Two inmates had jimmied their cell doors and then attacked Officer McGuinn on the fourth tier as he walked past their cells. He was stabbed repeatedly in the neck, head, thighs, and back in areas not protected by his stab-vest. He was able to break free and retreated down two flights of stairs before he collapsed. Other officers immediately came to his assistance. He was transported to a local hospital where he succumbed to his wounds one hour later.

One of the inmates was found incompetent to stand trial. On February 9, 2012, the other inmate was convicted of first degree murder. He was subsequently sentenced to life in prison without the possibility of parole.

Officer McGuinn had served with the Maryland State Division of Correction for two years. He is survived by his daughter and fiancee.
