The first of two teenagers charged in the stabbing a Lee's Summit woman to death in November 2015 is scheduled to go on trial beginning Monday.

Trevon Henry, 17, is charged with first-degree murder, robbery and two counts of armed criminal action in the death of 43-year-old Tanya Chamberlain. He waived his right to a jury trial and is set for a bench trial at the Eastern Jackson County Courthouse.

Henry's alleged accomplice, Joshua Trigg, is scheduled to go on trial beginning Nov. 26. Trigg was 14 at the time he and Henry allegedly ambushed Chamberlain one night at a car wash, drove away in her car and stabbed her before fleeing a police officer who tried to pull the vehicle over. Both defendants were certified to stand trial as adults.

JOHN RECTOR HOMICIDE: One of the defendants charged in the November 2016 murder of 84-year-old John Rector at his rural Eastern Jackson County home pleaded guilty this week.

John Lane, 19, of Kansas City, had been scheduled to go on trial Tuesday, facing charges of second-degree murder, armed criminal action and burglary. He pleaded guilty to the murder charge, and the state dismissed the other two charges, as Lane also pleaded guilty to burglary case and two tampering with motor vehicle charges in separate cases.

He is scheduled to be sentenced Nov. 29.

Lane's co-defendant in the case, 33-year-old Mary Couts of Blue Springs, faces the same charges Lane did and is scheduled to go on trial Nov. 26.

PHILLIP ANDERSON HOMICIDE: Anderson, 18, was a passenger in a car driving onto Interstate 70 from Noland Road on October 2017 when he was shot by the driver of another vehicle. Another passenger in Anderson's vehicle, 19-year-old Donavan James of Kansas City pleaded guilty in August to involuntary manslaughter, armed criminal action and unlawful use of a weapon, and he received concurrent sentences of seven, three and four years.

James, who initially had been charged with second-degree murder, had “aired out” – fired multiple rounds into – the vehicle driven by Michael Dumas in the area of I-70 and Noland after Dumas had apparently been “mean-mugging” Anderson and James' vehicle at a nearby gas station.

Dumas then followed the other vehicle onto I-70 and fired his handgun. Anderson and James' vehicle pulled into the QuikTrip at Sterling Avenue and U.S. 40 at the next exit, where police found Anderson dead.

James also pleaded guilty in separate cases of stealing a motor vehicle and was sentenced to four years each for those crimes – also concurrent to the manslaughter conviction.

Dumas, charged with second-degree murder and armed criminal action, was found later that night. He is scheduled to go on trial Jan. 7, 2019.

COREY LAYKOVICH HOMICIDE: The trial for John Seger, accused of fatally stabbing Corey Laykovich near the victim's Independence home in July 2013, is scheduled for Nov. 13. The trial has been postponed three times since September 2017.
