East Texas man gets 99 years in estranged wife's death in case that prompted national campaign

An East Texas man has been sentenced to 99 years in prison after pleading guilty to fatally stabbing his estranged wife in a case that prompted a national campaign.

A jury on Thursday sentenced 36-year-old Brad Dunn in the 2013 death of Kari Dunn. He was accused of dragging her into a bathroom and fatally stabbing her after she took their three children to visit him at a hotel in Marshall.

Her daughter tried to call 911 but was unsuccessful, not realizing she had to dial '9' to get an outside line.

Kari Dunn's family launched a campaign to make all hotels allow guests to dial 911 without having to first press another number.

Brad Dunn had pleaded guilty to murder on Tuesday. He also was assessed a $10,000 fine.
