( CNN ) -- It took five days for Colorado authorities to realize a parolee disabled his ankle monitor and fled , beginning what investigators would later say was a deadly crime spree that ended in a shootout in Texas , according to records released Tuesday . The documents released by the Colorado Department of Corrections detail how 28-year-old Evan Ebel managed to elude authorities in the days leading up to the killings of prisons chief Tom Clements and part-time pizza deliveryman Nathan Leon . The state Department of Corrections did not respond to repeated requests from CNN for comment . The release of the documents follows news this week that a clerical error resulted in Ebel 's release four years early from prison . That revelation prompted an apology from the district court where the mistake was made . Ebel was sentenced to eight years in prison in 2005 for armed robbery . In 2008 , he was sentenced to another four years -- to be served consecutively -- for punching a prison guard . A clerical error listed Ebel 's four-year sentence as concurrent , meaning he would not have to serve additional time beyond his original sentence . For Leon 's wife , it was too little , too late . `` Clerical error ai n't going to bring my husband back , '' Katherine Leon told CNN affiliate KUSA . `` [ It ] ai n't going to bring Tom Clements back . It 's not going to bring my children 's father back . How do I tell my 4-year-old ( that ) daddy was murdered because of a clerical error ? '' Authorities have speculated Ebel might have killed Leon for his uniform so he could use it as a disguise in the killing of Clements , who was gunned down after he opened his front door . Investigators have said they are looking into whether Ebel , a member of a white supremacist prison gang , might have conspired with other inmates to kill Clements . The corrections chief earned widespread recognition not only for prison reforms but also for a crackdown on prison gangs , including the white supremacist 211 Crew , who once counted Ebel among their ranks . Ebel was released from prison on January 28 , according to the records . Between his release and March 13 , Ebel appeared to comply with his parole , which required he wear an ankle monitor , check in daily with parole officials by phone , abide by an 8 p.m. to 6 a.m. curfew and stay out of bars , the records show . Ebel told prison guard she would 'beg for her life ' The first indication something was wrong came March 14 , when the ankle monitor gave off a `` tamper alert . '' Here is a timeline of how Ebel managed to elude authorities , according to the corrections department documents and previous statements by authorities : . March 14 . Ebel made his daily telephone call to check in with parole officials at 7:20 a.m . The `` tamper alert '' went off at 1:54 p.m. , and the company that oversees the monitoring system -- known as HomeGuard 206 -- notes the alert at 3:21 p.m . Initially , the ankle monitor was listed `` for repair '' and a message was left for Ebel to make arrangements to fix the ankle monitor . By 11:15 p.m. , Ebel had not checked in for messages . March 15 . Ebel failed to check in with parole officials , and a message was left for him to report to an appointment scheduled for the next day to repair his ankle monitor . Ebel again failed to pick up messages . His whereabouts , at this point , were unknown . March 16 . The `` tamper alert '' for Ebel 's ankle monitor was still active , and he failed to show up for an appointment to repair the monitor . March 17 . Contractors who oversaw the ankle monitoring of inmates notified parole officials that Ebel failed to `` make contact '' to have his ankle monitor repaired . Authorities believe this was the same day that Ebel killed Leon , the pizza deliveryman , whose body was found in the suburban Denver community of Golden . March 18 . Parole officials contacted Ebel 's family to inquire about his whereabouts . March 19 . Parole officials searched Ebel 's residence and determined he left quickly or went into hiding to avoid arrest . They begin paperwork to revoke his parole . That night , Clements was shot to death at his home outside Colorado Springs . March 20 . The state Department of Corrections issued a warrant for Ebel 's arrest , citing parole violations . March 21 . Ebel was killed in northern Texas in a gun battle with authorities that left a sheriff 's deputy wounded . CNN 's Carma Hassan , Dana Ford and Mark Morgenstein contributed to this report .
