WATERLOO (KWWL) -

Documents show on November 14th, John Derifield pointed a gun at his wife, her children, and also pointed the gun on himself threatening suicide.  

After a mental evaluation, Derifield was placed on pre-trial services - which is often similar to probation.

He bonded out of jail three days after being arrested in November..

He was placed on pre-trial services.

"Its to allow them to be back out in the community, but have certain conditions to meet so they make all their court appearances and so they don'tcommitt new crimes," says Karen Herkelman of the Department of Correctional Services.

Corrections officers also assess a "Lethality Score".

They're based on a series of questions officers ask domestic violence victims.

"If someone is arrested and placed in jail, we will go in and assess their risk to flee or commit new crimes," Herkelman says.

Derifield received a score of four - which indicates domestic violence was occurring in the relationship.

Higher scores than that indicate higher risk.

KWWL requested to talk to the officer handling Derifield's case - but that person isn't allowed to comment.

So it isn't clear whether there was any indication he would commit a crime.
