A Port Huron man accused of killing a woman in an alleged drug deal gone wrong will go on trial next month.

Robert Tonchen appeared before St. Clair County Circuit Court Judge Cynthia Lane for a plea hearing on Tuesday. Tonchen’s attorney and the prosecution said no agreement was reached.

The date for the jury trial is set for July 13.

Tonchen is charged with open murder, tampering with evidence, fourth degree arson and habitual enhancement fourth offender in the murder of Stephanie Thompson.

Tonchen was charged after Thompson was found dead in a parked car on Vanness Street in January.
