Det. David Garcia led the investigation. He and Lt. Chris Lamaine arrested Theresa Burden, 37, of 71 Sachem Drive in Shelton, Feb. 26 for four counts of first-degree threatening. She was held on $50,000 bond.
Burden is a student of the St. Vincent’s School of Nursing, and the charges stem from threatening letters containing a suspicious substance that have been sent to the hospital commencing on Dec. 12, 2012.
The letters caused alarm on numerous occasions within the institution, resulting in the hospital closing portions of the facility until the substance could be analyzed by state and federal authorities.
Burden was arrested at her home without incident and the motive for sending the letters has not been established. The investigation is ongoing, according to Capt. James Viadero, head of the Bridgeport detective bureau.
The state police are currently investigating a similar case in which threatening letters containing a similar substance were sent to Gov. Dannel Malloy. No arrest has been made in that investigation.
