A Massachusetts woman charged with fatally poisoning her boyfriend with a chemical commonly found in antifreeze and deicing fluid pleaded not guilty to murder and was held without bail at her arraignment Friday.

Judy Church, 64, of Salisbury, is charged in the death of Leroy Fowler, according to the Essex district attorney's office.

Church called 911 at about 8 p.m. on Nov. 11 to request an ambulance for Fowler, 46, authorities said.

Responding emergency personnel found Fowler in "obvious medical distress," the DA's office said.
