An Alabama man accused of murdering two people and severely wounding another has died by suicide.

Cullman County Coroner Jeremy Kilpatrick told news outlets that 30-year-old Matthew LeWayne Clayton died Tuesday at the hospital after a suicide attempt in his cell over the weekend.

Sheriff Matt Gentry said last week 76-year-old Thomas Frank DeWille and 75-year-old Rollan Frank Edwards were found dead with fatal knife and gunshot wounds.

Forty-eight-year-old Jody Jay Tudor was found with similar wounds and was later hospitalized. His condition is unclear.

Gentry says the attack seemed to stem from a past dispute.

He says the victims all lived together near Clayton, who was arrested near Interstate 65 after crashing his car.

Al.Com says DeWille was a concert pyrotechnics innovator who worked with Kiss and Bon Jovi.
