FAIRFIELD, Conn. (AP) - Police in Connecticut say a woman who ran an unlicensed daycare at her home and is charged in connection with an infant's death purchased 90 bottles of children's Benadryl over three years.

Fifty-three-year-old Carol Cardillo of Fairfield pleaded not guilty Tuesday in Bridgeport to charges including second-degree manslaughter.

Police have said the 4-month-old child found unresponsive at Cardillo's home in March may have been given the antihistamine, which isn't for children under 2. Officials ruled the death a homicide and determined the cause to be acute diphenhydramine intoxication.

An arrest warrant says Cardillo made the Benadryl purchases between 2013 and 2016 when her home daycare was open.

Police say Cardillo's attorney told detectives his client told him she didn't have the medication in her house.

Cardillo's attorney didn't comment Tuesday.
