The Department of Correction has confirmed convicted killer Nasser Hamad has died.

Deputy Communications Chief Sara French said Hamad died Sunday at 9:29 p.m. at Franklin Medical Center.

She said Hamad’s death was medically expected and the cause of death is tentative, pending receipt of the death certificate.

Hamad was serving a life sentence after being convicted on two counts of aggravated murder and six counts of attempted aggravated murder with firearm specifications.

Hamad was convicted in the shooting deaths of 20-year-old Josh Williams and 19-year-old Josh Haber outside of his Howland home in February. Forty-three-year-old April Trent, 20-year-old Bryce Hendrickson and 17-year-old John Shively were injured in the shooting.

Hamad maintained that he shot the group in self-defense, fearing for his life, after they showed up at his house to fight him.

However, prosecutors said Hamad coaxed the group to come to his house and after shooting at them, went into his house to reload his weapon before going back outside to fire at them again.

In March, he asked for parole due to a terminal illness. He said he was diagnosed with renal cell carcinoma, a type of cancer.

Hamad’s attorney, Geoffrey Oglesby, asked the court to grant Hamad parole just four months into his life sentence. The complaint he filed alleged Hamad wasn’t getting proper care at the Marion Correctional Institution.

Oglesby said he dismissed that complaint because Hamad was then getting the medical care he requested. He said he was being treated at the James Cancer Care Center at The Ohio State University.

In August, Hamad filed an appeal, saying he wasn’t given a fair trial. He maintained that his actions fell more under a voluntary manslaughter charge due to being attacked prior to the shooting.
