KANSAS CITY, Mo. — A Lee's Summit teen was sentenced Friday to two consecutive life sentences plus 50 years for the 2015 fatal stabbing of a woman at a car wash.

Trevon Henry, who is now 18 but was 14 at the time of the murder, pleaded guilty in October to first-degree murder, armed criminal action and first-degree robbery.

Joshua Trigg, now 16, also pleaded guilty to the same charges in the incident. His sentencing is set for Jan. 31 in Jackson County Court.

The teens are accused of killing Tanya L. Chamberlain in November 2015. Officials said surveillance footage showed the teens approaching Chamberlain multiple times before attacking her, stabbing her 49 times.

Later, a Lee's Summit police officer attempted to stop Chamberlain's vehicle but the teens sped off before ditching the car and running on foot. They were later arrested, and Trigg admitted that Henry stabbed the victim multiple times.
