HARRISBURG, Pa. (AP) — The Latest on the retired state trooper who police say fatally shot two Pennsylvania Turnpike workers (all times local):

4:20 p.m.

Police say a toll collector purposely tied the hands of a co-worker loosely when a retired state trooper tried to rob a Pennsylvania Turnpike toll booth complex. They also say the co-worker tried to take the gun away before the ex-trooper shot him and another man.

A search warrant affidavit released Monday said Martha Delores Berkstresser was finishing up the overnight shift at 7 a.m. Sunday when retired trooper Clarence Briggs walked up to her booth and pointed a gun at her and Danny Crouse, who was there to relieve her.

The state police affidavit says Briggs ordered them into a building and told her to tie Crouse's hands behind his back, but Crouse was able to get free and confront Briggs.

Police say Briggs killed Crouse and Ronald Heist, who was in a turnpike-owned van that pulled up during the robbery.

A state trooper later shot and killed Briggs.

Court records show a retired state trooper who police say fatally shot two Pennsylvania Turnpike workers and robbed an armored car collecting fare money filed for bankruptcy last year and had been accused of domestic assault.

Federal bankruptcy records say Clarence Briggs and his wife Donna had debts of $315,000 when they sought protection in March 2015.

Police say that on Sunday, Briggs shot and killed turnpike employee Danny Crouse and Ronald Heist, who was working in turnpike security, at the rural Fort Littleton toll plaza west of Harrisburg. Briggs was shot and killed by police.

His bankruptcy lawyer, Chad Julius, says he's in shock.

Assault and harassment charges against the 54-year-old Briggs were dismissed four months after they were filed in March 2014. He patrolled the turnpike before retirement in 2012.
