Another accomplice of Tay-K in the 2016 murder of Ethan Walker has pleaded guilty, leaving only "The Race" rapper and one other suspect awaiting trial.

According to an Aug. 30 report from the Star-Telegram, Sean Robinson, who was originally charged with capital murder, pleaded guilty to murder in exchange for a 40-year prison sentence on Thursday (Aug. 30). Robinson will serve 18 of those years behind bars due to credit for time served before he is eligible for parole.

"It's one more down and a couple to still go," said Richard Walker, father of Ethan Walker.

Robinson becomes the latest accomplice to plead guilty to a charge, following Ariana Bharrat, who recently pleaded guilty to aggravated robbery in exchange for a 25-year prison sentence.

Like Bharrat, prosecutors also struck a similar deal with Megan Holt, who was given the option to testify truthfully against Tay-K, Robinson and Jalen Bell in exchange for a 20-year prison sentence.

While Tay-K continues to sit behind bars, a photo of the rapper inside a jail cell was posted on his Instagram account on Aug. 28. The picture was uploaded two weeks after it was reported that Tay-K had been moved to solitary confinement in a maximum security center after it was discovered that he had a cell phone and charger hidden on him.

Along with the capital murder charge for the death of Walker, Tay-K also faces an additional murder charge for the fatal shooting of Mark Saldivar in San Antonio, Texas and an aggravated robbery charge for an Arlington, Texas incident.
