Roderick Tademy Trial: Joliet Man Saw Vampires Before Shooting His Son, Wife Testifies

The criminal trial against a Joliet, Ill. man accused of shooting his 12-year-old son began Thursday with remarks from the boy's mother who says her husband suffered from delusions.

Roderick Tademy, 37, suffered from schizophrenia and "thought he saw vampires" when he allegedly shot his son in the head on Dec. 20, 2010, his attorneys told jurors Thursday, according to the Chicago Sun-Times. Antoinette Tademy said her husband had started drinking at 7 a.m. that day and finished half of a large bottle of vodka before the incident. She said alcohol often exacerbated his delusions.

Joliet police had no prior contact with the family, who moved to the Chicago suburb nearly four years ago from the Atlanta area, according to the Chicago Tribune. Tademy was a stay-at-home dad who neighbors say they often saw walking his son, Obedyah, and twin daughters to school.

On the day Obedyah was shot, Antoinetta Tademy told police that he and her husband were arguing, and Roderick accused Obedyah of molesting his then-6-year-old sisters, though there is no evidence of any mistreatment, CBS Chicago reports. After shooting his son, Roderick Tademy told his wife he was "losing his mind" and tried to take his own life, but the gun jammed and she was able to recover it before fleeing.

Obedyah is now in a long-term care facility and cannot breathe, walk or talk on his own, according to the Sun-Times.

Roderick Tademy is facing attempted murder and aggravated battery charges.
