Investigators initially thought Moylan had been hit by a stray bullet, but later realized the couple's story did not match up, Mascara said.
The couple finally told authorities that April Moylan sleeps with a loaded .32-caliber revolver under her pillow. They said that when the burglar alarm sounded at about 4 a.m. Tuesday, she grabbed the gun and it accidentally discharged, shooting her husband in the head just behind his ear.
Mascara said the couple told authorities they couldn't simply call 911 because both are convicted felons and are not allowed to own a gun so they concocted the headache story.
April Moylan previously had been convicted of sale and delivery of cocaine in Palm Beach County, Mascara said. Her husband's criminal record was not immediately available.
