COUNCIL BLUFFS, Iowa (AP) — A western Iowa woman has been sentenced to life in prison without the possibility of parole in connection to the torture of her mentally disabled stepson. The Council Bluffs Daily Nonpareil reports 47-year-old Rebecca Beyer received the sentence Thursday at the Pottawattamie County Courthouse.

Authorities said Beyer abused the man, now 21, in February 2013. She was convicted in May of first-degree kidnapping and willful injury causing serious injury. The man testified that Beyer burned him and locked him inside a garage. He said he was attached to a wall with a dog leash.

The man’s father faces charges in the case, and his trial is scheduled to start in August. The man’s stepbrother pleaded guilty earlier this year to an accessory charge as part of a plea deal.
