The original version of this story said Kirtley was arrested Friday on a new charge. The arrest log for the Ada County Sheriff's Office showed she was taken into custody that day but did not indicate it for for an old charge.
Nicole Lee Kirtley, 35, was charged Friday for allegedly driving under the influence of intoxicants in an incident that occurred Oct. 13, 2012.
A criminal complaint was filed in that case on Feb. 4, 2013, and a warrant was issued for Kirtley's arrest the following day. Before she was taken into custody, she allegedly shot George Richardson Jr. multiple times at his home in the 1900 block of Powerline Road in Nampa, on Feb. 7, 2013.
Because Kirtley has two previous drunk driving convictions during the past 10 years, she was charged with felony driving while intoxicated. She was arrested for drunk driving on May 17, 2011, and again two days later. Both of those arrests took place in Caldwell.
She was found guilty in both of those cases and sentenced to 180 days in jail, with 130 days suspended.
Last month, Kirtley pleaded guilty to manslaughter, possession of a firearm during commission of a crime and destruction of evidence in Richardson's death.
In exchange, prosecutors downgraded a second-degree murder charge to manslaughter and dropped a charge of grand theft, for stealing Richardson's Jeep.
Prosecutors will recommend that Kirtley serve between nine and 30 years in prison. Sentencing before Third District Judge George Southworth is scheduled April 1.
Authorities said Kirtley, who lived in Melba at the time, left a Nampa bar after midnight on the day of the murder with Richardson. A surveillance video showed Kirtley taking Richardson's car keys and driving him away from the bar in his Jeep.
A witness told investigators a woman matching Kirtley's description was seen later that morning driving away from Richardson's home driving Richardson's red-and-black Jeep Wrangler.
The vehicle was later found partially submerged in the Snake River. A rock held the gas pedal down.
An affidavit filed in Third District Canyon County Court claims Kirtley admitted, during a conversation with another jail inmate, that she killed Richardson. She told the inmate she didn't feel bad about killing Richardson, saying she "wasn't going to be raped again," according to the affidavit.
