(Michigan City, IN) - A Michigan City man is charged with killing a woman by poisoning her with windshield washer fluid.

Thomas Holifield, 59, is scheduled for his next hearing in La Porte Superior Court 1 on January 20. According to court documents, 64-year old Pamela Keltz died on June 1.

Holifield allegedly told police he had a romantic relationship with Keltz, but more recently, they had been just friends. He was renting a room from her when he felt disrespected by the woman. 

Initially, he tried poisoning her by placing eye drops in her cup of soda, but the symptoms experienced by the woman were not severe enough. Hence, he turned to windshield washer fluid, according to court documents.

Authorities said that windshield washer fluid contains methanol, the lethal ingredient listed in her cause of death.
