Two adults and two children were found dead in a Hudson Valley home, next to a school.

Police in Pleasantville found the dead bodies of two adults and two children inside the home on Romer Avenue while making a welfare check after children didn't report to school. Sources tell ABC, it appears the man killed his wife and two young children in a murder-suicide.

It's not clear how the victims died and their identities haven't been released, CBS reports.

Pleasantville High School is located on Romer Avenue. A winter concert was canceled due to the police investigation, according to ABC.

"Our hearts are broken due to the tragic loss of life that occurred in our community today -including the deaths of 2 children. It is important that we support our staff, students and families with a compassionate circle of care. Our schools will be open tomorrow and counseling services will be available for students and families," Pleasantville Superintendent Mary Fox-Alter said. "Please remember that this is an on-going investigation and there will be an increased police presence in the area."
