Utah authorities had been worried Ellenwood would run. The arrest warrant and aggravated murder charge were filed under seal April 26 in Utah's 2nd District Court so as not to alert Ellenwood before he was arrested.
Weber County Attorney Dee Smith on Wednesday said Ellenwood's DNA matched evidence found in Odle's room.
Ogden police say Odle's killer about 2 a.m. on May 3, 1993, climbed through a ground-level unlocked window and entered her room at a retirement home at 2433 Adams Ave. After the suspect sexually assaulted and beat Odle, he was getting dressed and doing up his pants.
That's when an employee, who had heard the unusual noises came in to check on Odle. He fled, wearing only his Levi's.
Odle was taken to the intensive care unit of McKay-Dee Hospital Center, where she died six days later as a result of the blunt force injuries to her head, chest and extremities.
Three hours after Odle's assault, Ogden police say a 57-year-old woman was walking to a bus stop that's two blocks from the retirement home when someone attacked and sexually assaulted her, stabbing her twice and robbing her of her purse. Her assailant matched the description of Odle's killer.
Prosecutors suspect it was Ellenwood, but they're still trying to determine whether they can charge him. The statute of limitations may have expired, depending on exactly how many days he's been in Utah when time on the statute runs and how many he's been out of state, when the statute doesn't.
Ellenwood's prior criminal history in Utah is short and dated. In November of 1993, he was convicted with carrying a concealed dangerous weapon, and in 1994, he pleaded guilty to aggravated assault both unrelated to the May 3 attacks. In 2001, he pleaded no contest to driving under the influence.
More recently, Ellenwood was convicted of aggravated assault in Idaho in 2002. He was released from an Idaho state prison in 2008.
On Wednesday evening, Ellenwood was in a jail in Juneau, Alaska. There was no indication when extradition proceedings might begin.
Odle's family did not provide comment on Wednesday.
