Local and state police are investigating the death Monday evening of a 13-year-old Yarmouth girl who is suspected to have taken her own life, authorities said.

The seventh-grade student at Harrison Middle School was found unresponsive in her home by family members about 6:15 p.m. Monday.

The girl was rushed to Maine Medical Center in Portland, where she died shortly after arrival, said Stephen McCausland, a spokesman for the Maine State Police.

Yarmouth police and rescue workers were the first to respond to the home, but called for assistance from state police, McCausland said.

An autopsy by the Office of Chief Medical Examiner is scheduled for Wednesday, McCausland said.

The Yarmouth School Department notified the community of the girl’s death in an email message shortly before 10 p.m. Monday.

“Our efforts at this time will be focused on supporting students and staff who may be impacted by this news,” Superintendent Andrew Dolloff wrote in the email. “To that end, social workers, counselors, and other school-based professionals will be available for students who may need support throughout the day tomorrow and for the foreseeable future.”

In a second statement to the community Tuesday, Dolloff expressed his condolences to the family.

“We are heartbroken for (her) family,” Dolloff wrote. He said the girl “has been described by her teachers as a bubbly, happy, compassionate young girl, and we are deeply saddened by this tragedy.”

The school canceled after-school activities Tuesday, and mental health professionals from around the state are being brought in to provide assistance to students, Dolloff said in a subsequent message to parents.
