LOWELL, Mass. (AP) — A resident of a Lowell homeless shelter accused of fatally stabbing a shelter worker is scheduled to go before a judge.

Pericles Clergeau is expected to be arraigned on a murder charge Monday in Lowell District Court.


Authorities say the 19-year-old Clergeau was "in an agitated state" and attacked Roldan, who had tried to calm him down.

The Lowell Transitional Living Center normally searches people who stay there, but because there are so many who show up for meals on the weekends that not everyone is searched.
