A 34-year-old man was sentenced to 23 years in prison for killing his father in a Port Charlotte home. Jeffrey Patrick Mulligan pleaded no contest to a second-degree murder charge prior to sentencing. Mulligan’s sister and boyfriend walked into a home in April 2017 to find Mulligan beating and smashing his father’s head. Deputies later responded and found Patrick covered in blood trying to clean the floor with a mop. Mulligan’s father, Patrick, was pronounced deceased after being found in the bathroom. Jeffrey Mulligan admitted that he had beaten his father and continued saying that he was sorry,” according to a statement from the state attorney’s office.
