PORT ST. LUCIE, Fla. — A woman was arrested Tuesday after her husband woke up in the middle of the night with a terrible headache and later learned he had a bullet lodged in his head. St. Lucie County Sheriff's deputies initially thought Michael Eugene Moylan had been hit by a stray bullet, but later realized the couple's story did not match up, Sheriff Ken Mascara said. April Moylan, 39, was arrested Tuesday and was in the process of being charged with attempted murder, Mascara said.
