A family of four was found dead in their Ohio home on Tuesday in what the Avon Lake Police Department suspects is a murder-suicide.

Authorities discovered the bodies of Jeffrey Hull, 50, Heidi Hull, 46, Garrett Hull, 9, and Grant Hull, around 1:20 p.m. during a welfare check.

Heidi Hull’s employer requested the welfare check after she didn’t show up for a conference call and no answered the front door of the family’s home.

After the officers “observed a suspicious condition” inside of the home, they requested backup. Police suspect Jeffrey Hull shot his wife and two children before killing himself.

A dog was also found in the home and transported to the Avon Lake Animal Clinic. However, it is unclear if the animal was wounded by the incident.

Bob Scott, the Avon Lake City School District Superintendent, later released a statement and confirmed the two children attended Erieview Elementary School.

“This afternoon, we learned the tragic news that we lost one of our Avon Lake families, including two students at Erieview Elementary School. We have arranged to have grief counselors at Erieview tomorrow morning to work with staff and students,” the statement read.

“Please contact the Principal or Counselor at your student’s building if your family is in need of assistance. It is important that we recognize this loss and offer help. This is a sensitive issue for children, and we suggest that you talk with your children about their feelings. Our thoughts and prayers go out to all of our students and families in the Avon Lake Community.”

The Ohio Bureau of Criminal Investigation will be assisting the Avon Lake Police department in the investigation.
