Four people are dead after what authorities believe to be a murder-suicide in Jackson County.

A 64-year-old father is accused of killing his estranged wife, their son and the son’s ex-wife before turning the gun on himself.

According to Sheriff Mike Ezell, deputies responded to a 911 call Thursday night regarding a reported shooting.

Upon arrival, the deputy heard a single gunshot from the house, which he believed to have been the suspect taking his own life.

64-year-old Thomas Griswold is believed to have fired the shot that ended his life after he shot his estranged wife 64-year-old Veronica Griswold, their 36-year-old son Bjorn Griswold, and Bjorn’s ex-wife 39-year-old Jillian Pavolini.
