A licensed practical nurse has been arrested for allegedly failing to give medications to four residents at a Canton health care facility.

The state Attorney General's Office announced the arrest of Krysta Davis, who worked at the Maplewood Health Care and Rehabilitation Center.

She's accused of failing to give four residents their medications and falsifying the medical records of those residents by indicating she had dispensed the medications.

Davis is charged with first and second-degree falsifying business records, endangering the welfare of an incompetent or physically disabled person and willful violation of health laws.

She could face up to 4 years in prison if convicted.

According to the AG's office, the drugs that were not dispensed included treatments for dementia, coronary artery disease, bi-polar disorder and other health problems.

The AG said Davis' actions were discovered before the residents were significantly harmed.

The activity was detected by a co-worker and reported by Maplewood Health Care and Rehabilitation Center.

"It is shameful and appalling that someone hired to take care of our most vulnerable citizens would abuse her position as a caregiver," said Attorney General Eric Schneiderman in a news release. "My office is committed to ensuring that anyone who abuses our sick and elderly is held responsible and prosecuted to the fullest extent of the law. "

According to the Canton Police Department, Davis is 27 years old and lives at 780 Tracy Road in Lisbon.

Davis was arraigned Wednesday by Town of Canton Justice Christopher Curley.

Davis pleaded not guilty and was released on her own recognizance.
