Former home health aide Diana Gladue has been sentenced to four years in prison for stealing jewelry worth tens of thousands of dollars from the home of a disabled Mystic woman.

Gladue, 52, has been incarcerated since September 2014, when Stonington police charged her with first-degree larceny.

She pleaded guilty to the charge in May and was sentenced Tuesday in New London Superior Court to 12 years in prison, suspended after four years served, followed by five years of probation.

At the sentencing, Dr. Shama Kajiji, whose mother was Gladue’s patient, read a lengthy statement detailing the impact of the crime on her family.

Many of the items that Gladue stole from the family home on Mixtuxet Avenue over the period of 1½ years were family heirlooms and one-of-a kind items that cannot be replaced, Kajiji said in the statement.

“The sadness and shock of losing almost 100-plus years of family history still haunts and saddens,” the statement said. “And I personally find this whole incident haunting and have difficulty relaxing and sleeping in my own home.”

Kajiji had contacted police in June 2014 after noticing the jewelry missing from her mother’s bedroom.

Police estimated the value of the stolen rings, bracelets, earrings, necklaces and pendants with diamonds, emeralds, rubies, pearls, opals and gold at more than $95,000.

During the investigation, police learned that between November 2012 and April 2014, Gladue and her boyfriend, John Glynn, sold 40 pieces of jewelry at Gold Star Pawn in Groton.

Through photographs provided by the store, which had held the items for the mandatory 10 days and sold them, Kajiji identified 29 of them as stolen from her home.

Gladue worked for Recovery Resources LLC of Norwich, according to police, who learned during their investigation that she has a criminal record that includes a 2002 conviction for sixth-degree larceny, a second 2002 conviction for sale of narcotics, possession of narcotics and violation of probation and a 2004 conviction for possession of narcotics.

At Gladue’s sentencing, Judge Hillary B. Strackbein ordered her to make restitution payments following her release from prison in the amount determined appropriate after a restitution study by the Department of Adult Probation.

The judge said Gladue is to pay the full amount should she come into a windfall or inheritance.

The judge prohibited Gladue from working at jobs caring for vulnerable people, such as the elderly or disabled, and ordered her to tell all prospective employees about her conviction.
