ERIE, PA. Co-workers' deaths spook remaining deliveryman

Authorities are still investigating the bizarre explosion death of one man.
ERIE, Pa. (AP) -- Of the three deliverymen working at Mama Mia's Pizza-Ria this summer, one mysteriously died when a bomb locked to his neck detonated soon after he robbed a bank and another died of an accidental prescription drug overdose.
The third deliveryman, Bill Johnson, now carries a chemical spray when he goes to work and sees FBI agents visiting the Erie pizza shop daily. His co-workers are "bewildered" by the deaths of Brian Wells on Aug. 28 and Robert Pinetti on Aug. 31 and regularly talk about the events of last month, Johnson said.
"I took a week off after it happened," Johnson told the Erie Times-News for a story Sunday. "I am still very, very cautious when I go out there at night. I try to keep it off my mind. Otherwise, I would just quit."
Just before he died, Wells told authorities he had been forced to rob the bank just outside of Erie by someone who locked the bomb around his neck. Police had surrounded the 46-year-old pizza deliveryman and were waiting for a bomb squad to arrive when the device detonated.
Mysterious delivery
Wells' last pizza delivery on the day he died was to a television transmission tower on a small access road. Johnson, who was scheduled to work that day at 4:30 p.m., said it was scary to think that he could have been sent to deliver that order.
Three days after Wells' death, Pinetti, 43, died of an accidental prescription drug overdose. The Erie County Coroner's office ruled his death was not related to Wells' death.
Pinetti had a history of substance abuse and tests showed methadone and anti-anxiety drugs in his system, Erie County chief deputy Korac Timon said.
Johnson, 65, said he did not know Pinetti well, but considered Wells a friend. He once asked Wells to work for him and Johnson said Wells agreed, even though he had plans for the day.
Johnson said that since Wells' death FBI agents have questioned him twice and business at the pizza shop has declined.
Authorities are trying to determine whether Wells was a willing participant in the bank robbery or whether he was accosted during that delivery.
"I just wish this would be cracked pretty quick," Johnson said.
