GROTON TWP., Erie Co. -- A 33-year-old man's death was reported to Erie County law enforcement on Sunday by his father and step-mother, but a few days later the couple was arrested and charged with his death.

David Arthur Jr. lived in an old farm-house on Billings Road in Groton Township with David Arthur Sr., 54, and Deborah Arthur, 46.

Sheriff Paul Sigsworth said the condition of David Jr.'s body was one of the "worst cases of neglect" he'd ever seen.

According to the Lucas County Coroner's Office, the body showed signs of horrific neglect including but not limited to sepsis and multiple deep sores and ulcers down to the bone on much of his body.

Deputies reported a deep impression in the bed indicating that he had not moved in a very long time.

David Jr. was also severely malnourished, weighing only 94 pounds. The last time his weight was recorded was in 2011 while staying at a nursing home. At that time, he was healthy, alert and weighed 300 pounds.

The sheriff says David Jr. went to live with his father in February 2011, and his step-mom who is an LPN was supposed to care for him.

David Jr. had been in a motor vehicle accident in 1999 and suffered a brain injury, but witnesses said he was otherwise healthy and able to function while on medications at the nursing home.

For an unknown reason, the sheriff said he had not seen a doctor since moving in with his father and step-mom.

Deborah and David Sr. have both been charged with involuntary manslaughter and failure to provide for a functionally impaired person.

They are being held without bond at the Erie County Jail in Sandusky and will be arraigned Friday morning.
