A man suspected of killing a Youngstown patrolman was arrested in the St. Petersburg, Fla., area, after tips and phone calls he made to friends led police to his capture.

Local, state and federal agents surrounded a motel and talked an unarmed Martin Louis Koliser Jr., 30, into surrendering Wednesday night.

His arrest came about two days after the point-blank shooting death of patrolman Michael Hartzell, 26, a 2è-year veteran of the Youngstown police force. Koliser also was suspected in the wounding of a barroom patron just before the patrolman was killed at 2:19 a.m. Tuesday.

Koliser, a recently released ex-convict, was arrested in Palm Harbor, Fla. He was taken to the Pinellas County jail in Clearwater and will face a murder charge in Ohio, said county sheriff department Sgt. Greg Tita.

Police went to the motel in Palm Harbor, about 20 miles north of St. Petersburg, based on tips.

A $40,000 reward for information was being offered by the city of Youngstown and anonymous donors. There was no immediate indication if a reward claim would be filed.

Police said Lisa Ferguson was one of many people who provided tips on Koliser's whereabouts.

Ferguson said she has known Koliser for years and learned he was heading to meet with her fiance in Tampa.

"If he was my friend, he still needed to go down. Friend or not, wrong is wrong," she said.

The reward money should go to the slain policeman's family, Ferguson said.

"I want people to know that I did it because it was the right thing to do," she said. "It could have been your family. It could have been my family."

Police spent more than four hours outside Koliser's motel room before negotiators talked him into surrendering, Tita said. Koliser was arrested without incident and no guns were found, Tita said.
