PORTLAND, Ore. (KOIN) — The convicted sex offender who tortured, maimed and sexually abused an 89-year-old woman has been sentenced to life in prison.

The Multnomah County District Attorney’s Office said 59-year-old Timothy Mackley pleaded guilty on Thursday for the aggravated murder of Marcine Herinck. He also pleaded guilty to murder, kidnapping, burglary and abuse of a corpse.

Herinck was reported missing on Sept. 19, 2018 and her body was found on Sept. 24, 2018 in the trunk of the car Mackley was driving. ​​​​​​She was last seen the day before when a family member took her home from a shift at a thrift store where she volunteered.

Mackley was caught on surveillance video in the shop, where Herinck family members say there may have been a confrontation between him and Marcine. 

Investigators said when they pulled him over, Mackley said he’d met a nice woman a few days ago and invited her to his house and “I did something I shouldn’t have, and I’m guessing that’s why you guys are here now.”

Along with Herinck’s body, police found chunks of broken concrete, a shovel and a claw hammer in Mackley’s trunk. 

According to the indictment, Mackley ​​​​​​kidnapped, sexually abused and tortured Herinck over a six-day span before killing her.

Herinck’s son, Jeff Herinck read a victim impact statement at the sentencing. It said in part: 

“You kidnapped, stuff my mom, Marcine Herinck, in your filthy dirty trunk, abused tortured and murdered my mom, an 89 year old, 98 pound woman, over the duration of her captivity. You are truly and animal … It’s obvious that her life meant nothing to you, but to her family and friends she meant the world. Mom always had a beautiful smile and a heart of gold. If you ever needed a helping hand or someone to listen she was always there. Mom will be missed by family, friends and her beloved church family. It is sad that you had no compassion. You will have plenty of time to think about your actions.”

The DA’s office said Mackley must serve a minimum of 35 years before being eligible to apply for parole.

Mourners remember Marcine Herinck as 'one of a kind'
