Police are investigating an apparent triple murder-suicide of a Nebraska family who were discovered on the day of one son's high school graduation.

On May 10, at around 9.45am, Nebraska State Patrol were called to a home at Johnson Lake, Plum Creek Canyon.

They arrived to find four people dead - all later identified as residents of the home and named as Jeremy Koch, 42, Bailey Koch, 41, and sons, Hudson, 18 and Asher, 16.

The results of a preliminary investigation is that Jeremy allegedly killed his sons and wife before taking his own life, a release by Nebraska State Patrol states.

A Facebook page details parents Jeremy and Bailey having established a community called Anchoring Hope for Mental Health - the high school sweethearts of over 25 years having been open about suicide publicly to help show others they're 'not alone,' alongside trying to raise awareness of the mental health crisis.

All four members of the family were reportedly found with fatal knife wounds and the knife located at the scene.

One of the sons was reportedly set to graduate from Cozad Community Schools, the school taking to Facebook to address the 'tragic situation'.

A statement reads: "Cozad Schools was made aware of a tragic situation that will deeply affect our Cozad community. Our thoughts are with all those impacted during this incredibly difficult time.

"Cozad Middle School will open at 12:30 today for grieving students and staff. The Cozad High School Graduation ceremony remains scheduled for 4:00 pm today. Seniors should report to the high school at 2:00 pm today.

"We appreciate the strength and support of our community as we come together in care, compassion and unity."

"We will also have support available for students and staff when school resumes on Monday."

The Dawson County Attorney has ordered autopsies of all four family members and the investigation remains ongoing.
