( CNN ) -- A Colorado convict serving time for attempted murder was recaptured Wednesday after breaking out of prison over the weekend , and a female hostage with him was released unharmed , prison officials said . Douglas Alward was caught near Yuma , Colorado , about 145 miles east of Denver and about 50 miles south of the Sterling Correctional Facility he broke out of Sunday , prison spokeswoman Katherine Sanguinetti told HLN 's `` Prime News . '' Alward , 48 , was serving a 20- to 40-year term for attempted murder , assault and kidnapping and had broken out of prison three times before , Sanguinetti said . He was up for parole in October , according to prison records . Investigators found him in a trailer near Yuma about noon Wednesday . He surrendered once confronted , releasing the woman with him without injury , said Ari Zavaras , executive director of the Colorado Department of Corrections . Zavaras said searchers tracked Alward to a 4-square-mile patch of cornfields outside Yuma on Wednesday morning . `` He did n't offer any resistance , let alone armed resistance , '' Zavaras said . Zavaras released few details of the escape , but said an investigation into how Alward broke out of the maximum-security facility was under way . He promised a `` top to bottom '' review was in the works . He said Alward `` breached '' the fence around the facility somehow , and some tools used in the breakout were found nearby . The fence was not cut , he said . Prison officials are looking at how Alward obtained the tools , but do n't believe he had outside help , Zavaras said . Kevin Milyard , the prison 's warden , said a guard noticed something wrong within an hour of the breakout , and an emergency head count quickly confirmed Alward was missing . Alward is facing a likely charge of escape and other charges that remain to be determined , Zavaras said .
Yuma broke out of an eastern Yuma prison Wednesday . He was recaptured Sunday about 145 miles away . A hostage with him was released unharmed , prison officials said .
