A Massachusetts man has been found guilty of first-degree murder nearly four years after his girlfriend was found dead in a marsh in Saugus. The Essex County District Attorney's Office said 48-year-old Bruce Maiben of Lynn would be sentenced Wednesday after a jury convicted him Monday. Sherell Pringle, a 40-year-old Woburn woman, was reported missing after she did not return home from a date with Maiben on Dec. 18, 2021. Family and friends found her body two days later in the Rumney Marsh Reservation off of Route 107 in Saugus. Maiben was arrested on charges of larceny over $1,200, tampering with evidence and obstruction of justice. Prosecutors later charged him with murder. Family and friends of Pringle have said they used technology to find out where her phone was — a catch basin on the side of the road — and backtracked from there. Then they saw a purse by the road. "What hurts the most is, I told these cops from the jump to locate Bruce Maiben," Pringle's son, Jahmani Larionne, said at the time. "I told them Day 1, 'You need to located Bruce Maiben. He lives in Lynn. You need to ping his phone and find him.'"
