BRIGHTON, N.Y. — Brighton Police say they had previous contact with Lawrence Mancuso, the man who, according to officers, killed his daughter, her grandmother, and himself.

The murder-suicide happened on Friday just before noon. Police found 11-year-old Anne Mancuso with gunshot wounds on a porch on Hollyvale Drive. She died at the hospital. Inside a home next door, police found the bodies of Lawrence Mancuso, Anne’s father, and 74-year-old Mary Liccini, Anne’s grandmother.

A GoFundMe has been set up to help Anne’s mother and other family members with memorial arrangements and the “ongoing costs of rebuilding her life.” The page says:

“We are rallying together to support Sarah and her family during this time of unbelievable loss and grief.”

Anne was a sixth grader in the Brighton Central School District. The district is offering counseling services to students and faculty. A statement from the district says in part:

“There are no words. I write to you with an extremely heavy heart and without the ability to accurately convey our sorrow, our horror, and our empathy in this moment. I can only express our deepest sympathies and our commitment to be there for all of you and each other as a Brighton Family.“

Cornell University confirmed that Lawrence Mancuso, 53, was the assistant dean for human resources in the School of Industrial and Labor Relations. The university said he had been on leave since October.
