Patty Wetterling told news media after Tuesday's plea hearing that it was "incredibly painful to know (Jacob's) last days, his last minutes," according to the Star Tribune. Still, she said, her son's legacy will continue.
“He’s taught us all how to live, how to love, how to be fair, how to be kind,” Wetterling said.
Jacob disappeared the evening of Oct. 22, 1989, as he rode home on his bike with his younger brother, Trevor, and his best friend. The three boys had gone to a nearby convenience store to rent videos and buy snacks.
The Star Tribune reported that Heinrich told the packed courtroom Tuesday that he was driving on a "dead-end road" in St. Joseph when he spotted the boys on their bikes with a flashlight. He stopped them and told the other two boys to run home and not look back.
Heinrich forced Jacob into the passenger seat of his car and handcuffed him, the newspaper reported.
“What did I do wrong?” Heinrich said Jacob asked.
Heinrich made Jacob duck down into the seat as he listened to a police scanner, which, after the other boys ran the half-mile back to the Wetterling home, crackled with news of the abduction. He drove Jacob to the gravel pit, where he walked him to a stand of trees.
It was there, Heinrich said, that he removed the handcuffs and Jacob’s clothes, and molested him. When the boy complained of being cold, he told him to get dressed.
Jacob asked to go home, but Heinrich told him he couldn't take him all the way home, at which point, the boy began to cry, the Star Tribune reported. Heinrich told the court he panicked and pulled out a revolver.
He said he told Jacob to turn away from him because he had to use the bathroom.
"I raised the revolver to his head. I turned my head and it clicked once. I pulled the trigger again and it went off. Looked back, he was still standing," Heinrich said, according to the newspaper. "I raised the revolver and shot him again."
Heinrich left, but returned later to bury Jacob’s body. He told the court that he moved the body a year later after he returned to the burial site and could see the boy’s jacket had begun to show through the soil.
The Star Tribune reported that Heinrich also detailed his molestation of another boy, 12-year-old Jared Scheierl, in Cold Spring, Minnesota, nine months before he abducted and murdered Jacob. Investigators long believed the two cases might be connected, due to the description of the suspect in each case, and Heinrich was tied by circumstantial evidence to the Cold Spring attack as early as February 1990.
He was physically linked to that case last year when DNA found on a sweatshirt Scheierl was wearing during the attack was matched to Heinrich's DNA profile, according to WCCO, Minneapolis' CBS affiliate. Prosecutors could not bring charges against Heinrich in that assault, however, because the statute of limitations had expired.
Heinrich was also considered a suspect in 1991 when several paperboys in the Paynesville area reported being followed by a tan vehicle while on their routes, the Star Tribune reported. Though Heinrich at the time drove a similar vehicle, no charges were ever brought in those cases.
