A rookie Connecticut State Police trooper remains on the job while her use of a Taser on a man who died four days later is the focus of an internal investigation.

Dash and body-worn video obtained by Hearst Connecticut Media Group shows state police Trooper Jessie Rainville using her stun gun on Ryan Marzi after she and state police Trooper Desmond Stimson responded to a report of a domestic violence incident at a Canterbury home on Aug. 24.

The sound of the Taser can be heard continuously for 1 minute and 2 seconds and ends when Stimson tells Rainville, "enough with that," according to the video footage.

Four days later, state police said Marzi, 38, was found dead in his family's Hebron home. The state Office of the Chief Medical Examiner is conducting more tests to determine his cause of death.

As required by state police policy, Rainville's use of the Taser is under review by her supervisor. State police have not yet responded to Hearst Connecticut Media's request for the log for Rainville's Taser showing exactly how long the device was deployed that night. State police have also not confirmed the length of time Rainville deployed the stun gun during the incident.
