A Minnesota man charged with attempting to kill his ex recruited his new girlfriend to “pull the trigger,” prosecutors say.

According to recently filed court documents, Colleen Purificacion Larson, 24, confessed to investigators that she and Timothy Allen Amacher planned the attack together about a week or two in advance of the April ambush on Nicole Lenway that left her in critical condition.

Amacher, a Taekwondo master authorities described as “prominent,” is currently charged with one count each of first-degree attempted premeditated murder, conspiracy, and aiding an offender as an accomplice after the fact. Larson is currently facing one count of first-degree attempted premeditated murder.

A report from May identified Lenway as a Minneapolis Police Department forensic scientist.

Amacher earlier this month sought to have the charges against him dismissed for lack of probable cause. Prosecutors responded last week with a court filing that included new information about the evidence the state has against Amacher, including an alleged confession from Larson.

According to prosecutors, Lenway arrived at approximately 7:18 p.m. on April 20, 2022 at the parking of FamilyWise, a parenting center to pick up her and Amacher’s 5-year-old son. At the time, Amacher was apparently inside the facility with his child for a weekly supervised visitation.

Surveillance footage allegedly shows Lenway waiting in her car for a few minutes. At approximately 7:21 p.m. a black truck with no license plates pulls into the parking lot and stops at the south end. Larson, wearing all black and a medical mask, allegedly gets out of the truck, walked past Lenway’s car, and then hid in some trees.
