Interesting article about Dissinger. I lived in that neighborhood when this happened. There were several suicides in Camp Hill that year. In fact, in the eighties, Cumberland County had the highest suicide rate in the state.
It is not unusual for someone who has made up his mind to commit suicide to get a burst of energy just before the act, and to do the things Dissinger did: go jogging; attend to the yard work, etc. Putting things in order.
One factor in his suicide, as well as those of other prominent people in that affluent neighborhood, may have been the abysmal mental health care given at the local hospital at that time. More than one patient recently released from the mental health unit there committed suicide right after getting out.
Now as to Ray Gricar: given his family history, he may have been brooding over his brother's death and may have decided to take the same way out. This happens in families that are prone to suicide.
However, I hope that is not the case, and that Ray will be found alive and well.
Gricar is still missing. His family made a TV appearance imploring him to return home. They sound as if they believe he has just taken some unscheduled time off.
PA State Police searched the river for an hour. They found nothing. However, the West Branch of the Susquehanna is full of submerged rocks, trees, and debris, and takes weeks or months to yield up its dead.
I hope Gricar is still alive.
