When the man who plunged a knife 51 times into their loved one received a sentence of life in prison in May 1993, Bryan Knoblich and his mother hoped they would never hear Tracy Province's name again.

In 1991, Province and David Rodacker were on leave from jail when they attacked Norman Knoblich, 57, as he closed his coin-operated laundry business in Tucson. The pair left Norman dead and took only his wallet.

Nineteen years later, Bryan Knoblich and his mother are again on the lookout for his father's killer.

Province, 42, John McCluskey, 45, and Daniel Renwick, 36, escaped from a privately run medium-security state prison in Kingman on Friday night.

"My first thought was, 'Are you kidding?' " Bryan said, recalling when he heard Province's name on the weekend news. "He's a twisted guy. Why weren't they in a maximum-security facility?"

It's a question Mohave County supervisors and other officials are asking as authorities continue their search for Province and McCluskey. Renwick was recaptured Sunday in Colorado.

"It's one thing when it's vehicular homicide and you're drunk," County Supervisor Buster Johnson said Monday of such prisoners. "But these people shouldn't be allowed anywhere else but in (maximum security)."

While the manhunt continues, officials with the county, the Arizona Department of Corrections, and Management and Training Corp., the Utah-based company that operates the facility, are studying how the men penetrated several layers of security.

Unarmed prison officials sounded the alarm about 9 p.m. after Province, McCluskey and Renwick missed their head count, Johnson said. An hour passed before the Mohave County Sheriff's Office was notified that the men somehow had made their way through locked doors and avoided surveillance cameras, ground and fence sensors, guard towers and roving ground patrols before cutting a hole in fencing near a dormitory.

Officials are now investigating whether the escapees had inside help.

"That's the question," Johnson said. "With this whole situation, this does bring up some concerns."

Authorities believe the men were assisted by McCluskey's fiancee, Casslyn Welch of Mesa. They are believed to have hijacked two semitrucks and driven to Flagstaff before purchasing a car in Goodyear.

Renwick was captured in Rifle, Colo., following a shootout with local authorities. No one was hurt and Renwick was booked into the Garfield County Jail.

Although state officials have said all three men were serving time for murder, court records show McCluskey was serving 15 years for attempted murder after he fired a shotgun into a Mesa home in March 2009. He told police he would have killed his target had his weapon not jammed, records say.

"He (McCluskey) also indicated that he would have shot the officer who detained him," court documents state.

The Kingman facility holds 3,508 inmates, according to Carl Stuart, a Management and Training Corp. spokesman.

Of those inmates, 117 are serving life sentences, with 57 being housed on first-degree murder and 60 on second-degree murder convictions, according to state corrections officials. The facility is classified as a medium-security prison, meaning it houses "inmates who represent a moderate risk to the public and staff," state Corrections Department Director Charles Ryan said in a release.

Prison officials are seeking bids to add an additional 5,000 beds at the prison, which means the facility could house inmates from other states, Johnson said.
