Wife of slain Austin jeweler says daughter-in-law Jaclyn Edison got away with murder

When "48 Hours" found Jaclyn Edison sitting on a bench with a book in her hand, we might have mistaken her for a young professional on her lunch break. But Edison wasn't on the job. She was on probation.

She was sitting in front of an Austin, Texas, jail, where she'd just finished serving time after pleading guilty in a 2018 murder plot that sent three others to prison for up to 35 years. So why did Edison get a sentence of 120 days behind bars?

"48 Hours" contributor Jim Axelrod reports on the crime – and the punishments – in "Shootout at the Shaughnessys,'" an all-new "48 Hours" airing Saturday, Jan. 13 at 10/9c on CBS and streaming on Paramount+.
