ST. LOUIS COUNTY, Mo. — Adrienne Simpson, the woman who went on a multi-state crime spree with her boyfriend in 2021 that left two people dead in St. Louis County, entered a guilty plea Thursday.

It was May 15, 2021, when Simpson went on the run with Tyler Terry after killing 71-year-old Barbara Goodkin and 58-year-old Dr. Sergei Zacharev in St. Louis County.

Both suspects were later found in South Carolina after committing two more murders in that state and one in Tennessee.

Simpson was charged with 14 crimes in connection with the St. Louis County incidents. She entered a guilty plea Thursday to two counts of first-degree murder, two counts of first-degree assault, two counts of unlawful use of a weapon, seven counts of armed criminal action and one count of first-degree robbery,

Simpson's sentencing was scheduled for Oct. 30.

Terry was also charged with 14 crimes, including murder, robbery and assault, in connection with the deaths of Zacharev and Goodkin. He previously pleaded not guilty; in July, he formally withdrew that plea and entered a guilty plea.

Terry was sentenced to life in prison without parole and multiple life sentences, which are all to run concurrently. Terry smiled the entire time as both victims gave their statements in July and laughed as he was escorted from the courtroom.

Terry and Simpson were already serving life sentences after they both pleaded guilty to killing Simpson's husband and another person on May 2, 2021.

Police said it's unclear why Terry and Simpson were in St. Louis County as they have no known connections to the area or the victims.

 Zacharev was shot to death and robbed in Brentwood while waiting for an Uber. 

Goodkin was killed while riding inside her SUV in University City along with her husband Stanley, who was also shot in the chest. His cell phone saved his life. Both shootings happened on May 15, 2021.

"This was a heinous crime that gripped the St. Louis metropolitan area, Rick Knox, executive director of the Major Case Squad of Greater St. Louis, said in a previous statement. "(Barbara and Stanley Goodkin) were just coming home from dinner and were assaulted on Del Mar Boulevard. Dr. Zacharev was just getting off an airplane coming back from Florida and just minding his business."
