Jesse Mathews avoided a death penalty trial by pleading guilty Friday to killing Chattanooga police Sgt. Tim Chapin.
He likely will die in prison.
District Attorney Bill Cox called the sentence a death penalty in itself.
"You go to the penitentiary; you stay there until you die," Cox said. "You wake up every morning knowing you're never going to leave until they carry you out."
Mathews replied with simple yes or no answers to Hamilton County Criminal Court Judge Barry Steelman's questions during his 40-minute hearing before Steelman accepted his guilty plea and handed down a sentence of life in prison without parole plus 25 years.
The guilty plea eliminates appeals for Mathews, something a trial would not, Cox explained.
Cox said defense attorneys Lee Davis and Bryan Hoss approached him with the offer of a plea for the life sentence Wednesday. He met with Chapin's family the same day to get their approval and then met with police staff Thursday.
Chattanooga police Chief Bobby Dodd said after the hearing that he hopes the sentence can allow the family, police and the community a chance to heal and find some kind of closure.
"Tim and I were friends; it was a tragic situation. It's almost like you're in a dream sometimes when something like that happens," he said.
Area law officers who have died by violence since 1975:
Sgt. Tim Chapin, Chattanooga Police Department. Shot by Jesse Mathews during botched robbery April 2, 2011.

Officer Harry Wilcox, Chattanooga Police Department. Shot to death with his own service weapon on Jan. 18, 1979. The suspect was found mentally incompetent to stand trial.

Officer Nelson I. Hess V, Chattanooga Police Department. Killed in same call as Friederichsen.
Chief Deputy Baxter Shavers, Catoosa County Sheriff's Office. Shot to death with his service weapon by a robbery suspect on April 14, 1978. Detective George Brown also was shot but survived. The shooter's death sentence later was reduced to life.
Patrolman Clarence E. Hamler, Chattanooga Police Department. Shot when he interrupted a grocery store robbery on Aug. 14, 1977. Hamler's brother picked up his weapon and shot one robber to death. The other was caught five months later and sentenced to death, later commuted to life.
"Hopefully he'll regret what he did for the rest of his life until he dies in prison," Dodd said of Mathews.
Davis said he had offered the plea to the district attorney for more than a year, but he understood it likely would take time for the family to process it and decide what to do.
"With this case now closed it allows Tim Chapin's memory to be the focus and not the potential of a death penalty for Jesse Mathews," Davis said. "When you're caught up in a death penalty trial; the victim is all too often lost."
The Chapin family declined to comment to the media after the hearing and said they would issue a statement later.
In February 2011 the 27-year-old Mathews fled a Colorado halfway house, where he was serving a sentence for armed robbery. He came to Chattanooga to meet his family, who had come here from North Carolina.
On April 2, 2011, he robbed the U.S. Money Shops store on Brainerd Road. When Chattanooga police arrived, he fired a .45-caliber pistol at them and ran.
Chapin confronted Mathews and the pair got into a brief gunfight before Mathews killed the veteran police sergeant.
