A Massachusetts man appeared in court on Wednesday for allegedly stalking a woman after police traced a GPS tracking device attached to her car back to the suspect.
Shaun Tyman of Lowell pleaded not guilty at his arraignment in Woburn District Court on charges of stalking and attempted breaking and entering.
The Winchester Police Department conducted a monthlong investigation into the alleged stalking before they arrested Tyman on Tuesday.
In court, prosecutors said there were two instances in which police say Tyman is allegedly seen on surveillance camera, stalking the victim, a coworker at Raytheon.
The first incident was at 1 a.m. on June 16.
"They saw someone walk into the driveway to the side of the home. The person went up to the screen door and was there for approximately six minutes, where he holds the screen door open and appears to be trying to get to the main entry door to open," said a prosecutor.
On June 19, police received a complaint from a Winchester resident that an unknown man was caught on video attempting to enter her home. That same video showed the unknown man crawling under her vehicle, where the GPS device was found.
"He walked into the driveway of the victim. Crouched down beside the rear of her driver wheel and appeared to be reaching under her vehicle," said the prosecutor.
After the GPS was analyzed and officials were granted subpoenas, a search warrant was issued for Tyman's home.
Authorities said Tyman and the victim work together in separate departments at Raytheon.
"He has and continues to cause me tremendous fear for my life and safety at all times," the victim stated in a police report. "I have installed security cameras, additional locks, alarms and have avoided going anywhere alone since June 16 due to the constant fear this man could appear anywhere at anytime."
Tyman was released on $1,000 bail, must wear a GPS monitoring device and was ordered to not be within 500 yards of the victim. He's due back in court sometime in August.
