Douglas, who was serving a 7½ -year sentence on weapons and theft charges, was arrested within two miles from where he walked away from a group of convicts working with Tucson city employees, according to the Department of Corrections.

But the manhunt continues for an inmate who broke out of an Arizona prison late last month. Corrections officials are expected to release a security review related to the escape of John McCluskey, 45, at about 10:30 a.m. Thursday.

The last known sighting of fugitive inmate John McCluskey and his cousin, who is also his fiancée, Casslyn Welch, was on Aug. 6 in Billings, Mont.

Since then, the case has gone cold.

Authorities have made four arrests in connection with the July 30 escape from a privately run prison near Kingman: McCluskey's mother and ex-wife for helping the fugitives and the two inmates who broke out with him.

Claudia Washburn, McCluskey's mother, was booked into Maricopa County's Fourth Avenue Jail on Monday afternoon as police were confirming that her son was not holed up in an apartment on Phoenix's northwest side.

Investigators believe Washburn gave her son and Welch -- who is both McCluskey's fiancee and Washburn's niece -- money when they came to the gas station Washburn operates south of Payson on the day after the escape.

But that was more than two weeks ago, and investigators believe McCluskey and Welch's resources are likely running out.

Authorities have connected the fugitives with the murder of a 61-year-old Oklahoma couple in New Mexico and believe they stole money from them, Gonzales said.

Investigators are combing through the backgrounds of McCluskey and Welch, looking for other connections that might sustain the fugitives.

While the manhunt is nationwide, there are few options where McCluskey and Welch could be hiding out. McCluskey, whose experience includes a 14-year stay in a Pennsylvania prison before he was sentenced to prison in Arizona in 2009, does not have the financial wherewithal to stay on the loose without committing crimes, Gonzales said.

With that in mind, investigators are receiving tips from around the country on such crimes as auto thefts, burglary and armed robbery.

McCluskey was affiliated with a White supremacist prison gang during his time in Arizona custody, and authorities say Welch told detectives she was smuggling drugs for the same gang when she was arrested in June and accused of attempting to smuggle drugs into McCluskey's prison.
