ORANGE, MASS. (WHDH) - Orange schools were in lockdown on Thursday and some roads blocked off after a home invasion Wednesday night that left one elderly man dead and his wife seriously injured.

Police Chief Craig Lundgren suggested the schools have students remain inside Thursday as a precautionary measure because the suspect was still at large, and police do not believe the invasion was an isolated incident. The shelter in place was lifted midday.

The Northwestern district attorney said the incident happened Wednesday night at the house on River Street. According to police, the woman was transported to UMass Medical Center in Worcester for treatment.

The Office of the Chief Medical Examiner will determine the cause of death of the man.

Investigators searched the house and a car on the property. Neighbors said they do not know who would want to hurt the couple.
