A man accused of kidnapping a 13-year-old Wisconsin girl and killing her parents is scheduled to appear in court Wednesday for a preliminary hearing.

Jake Patterson, 21, is accused of killing James and Denise Closs on Oct. 15 and kidnapping their daughter , Jayme Closs, from their Barron home. Jayme escaped on Jan. 10, after 88 days.

Patterson is expected to be in the courtroom Wednesday, according to Sheriff Chris Fitzgerald. The purpose of a preliminary hearing is to determine whether there's grounds for a trial. Both sides can present evidence.

According to the criminal complaint, Patterson told investigators he knew Jayme "was the girl he was going to take" after he saw her getting on a school bus near her home. He made two aborted trips to the family's home before carrying out the attack in which he killed Jayme's mother in front of her.

In the days that followed, thousands of people volunteered to search for Jayme. Investigators believe Patterson hid Jayme in a remote cabin in Gordon, about 60 miles (97 kilometers) north of Barron, before she escaped and got help from a woman walking her dog.

Jayme told police that on the night she was abducted, she awoke to her dog's barking, then woke her parents as a car came up the driveway. Her father went to the front door as Jayme and her mother hid in a bathtub, according to the complaint. Jayme told police she heard a gunshot and knew her dad had been killed.

The involuntary manslaughter conviction of a young woman who encouraged her boyfriend through dozens of text messages to kill himself was upheld Wednesday by Massachusetts' highest court.

The Supreme Judicial Court agreed with a lower court judge who found that Michelle Carter caused Conrad Roy III's death when she told him to "get back in" his truck that was filling with toxic gas after he told her he was scared. The judge said Carter had a duty to call the police or Roy's family when she knew he was killing himself.

"And then after she convinced him to get back into the carbon monoxide filled truck, she did absolutely nothing to help him: she did not call for help or tell him to get out of the truck as she listened to him choke and die," Justice Scott Kafker wrote in the Supreme Judicial Court's ruling.

Carter's lawyers noted the only evidence she instructed Roy to get back in the truck was a long, rambling text she sent to a friend two months later in which she called Roy's death her fault.

Carter was 17 when Roy, 18, was found dead of carbon monoxide poisoning in July 2014. Carter, now 22, was sentenced to 15 months in jail, but has remained free while she pursues her appeals.

Prosecutors had argued Carter could have stopped Roy from killing himself, but instead bullied him into going through with his plan through text messages that became more insistent as he delayed.
