Teacher died breaking up fight between boyfriend, girlfriend

He said Fitchburg Police, as well as State Police detectives assigned to his office and State Police forensics experts, continued to investigate the case.

The city fire department was notified that the teacher was having difficulty breathing by a retired firefighter who works at the school and is also an EMT. The retired firefighter and the school resource officer both administered CPR, Deputy Fire Chief Kevin Curran said.

Two ambulances with four crew members aboard were dispatched to the school, said Chief Kevin D. Roy. They intubated the teacher and continued CPR.

Crews took the man to nearby Leominster Hospital, arriving by 8:01 a.m., Curran said. But he was not breathing when they arrived, he said.

Lloyd had worked at Mount Wachusett since 2008 as an MCAS biology instructor in a college preparatory program at Fitchburg High School.

In a statement, Mount Wachusett Community College President Daniel M. Asquino said Lloyd's colleagues were "deeply saddened over his loss."

"He was a very popular and passionate educator who cared deeply about his students," he said. "As always, he was acting in the best interest of his students today and what happened was an unfortunate tragedy that no one could have predicted."

The death marred what is normally a happy day each year at the high school. The school's graduation was set for today, according to a calendar posted on the Web.

"Everybody's miserable," said Saleem Kidd, 17, a sophomore. "We're not doing any schoolwork. We're just waiting for school to end."
