Suspect in killing of Amber Guyger murder trial witness moved to Dallas jail 4 years later

A man accused of killing a witness in former Dallas police officer Amber Guyger’s murder trial in 2019 has been transferred to Dallas County after spending time in a Louisiana prison on unrelated charges, officials said.

Thaddeous Green, 26, was booked into the Dallas County Jail on May 18, according to police records, and faces a charge of capital murder in the death of Joshua Brown.

Brown was fatally shot the night of Oct. 4, 2019, in the parking lot of the Atera Apartments near the Oak Lawn neighborhood of Dallas, police said.

Two other suspects, Michael Mitchell and Jacquerious Mitchell, were taken into custody less than a week after the shooting. Police said Green shot Brown during a drug deal.

Jacquerious Mitchell was wounded in the confrontation with Brown. He told detectives that Green contacted Brown about a drug deal and traveled with the two other suspects from Alexandria, Louisiana, to meet Brown, police said.

Green and Brown got into a fight at Brown’s apartment complex, according to police. Brown shot Jacquerious Mitchell in the chest when he got out of the car, police said. Green is accused of shooting Brown and taking his backpack and gun.

Brown was 28 at the time of his death. He was the former neighbor of Botham Jean, the man who was fatally shot in his own apartment by Guyger in September 2018.

Brown testified in court at Guyger’s murder trial on Sept. 24, 2019, just days before he was fatally shot.

Guyger was convicted of murder and sentenced to 10 years.

Court records show that Michael Mitchell, 35, pleaded guilty in November to murder in connection with Brown’s death and was sentenced to 40 years. Jacquerious Mitchell, 23, is awaiting trial on a capital murder charge and is still in the Dallas County Jail.

Green’s bond was set at $2 million for the capital murder charge, according to jail records, but he cannot be released on bond because of the unrelated charges he was serving prison time for in Louisiana.

Green was arrested in Jefferson Parish, Louisiana, on Dec. 19, 2021, and convicted of using a firearm while in possession of a controlled substance and escape from the custody the Jefferson Parish Sheriff’s Office, according to court records.

Green pleaded guilty to both charges and a Louisiana judge sentenced him to six years in prison. It’s not clear if that sentence would run concurrent of any time he would receive if convicted of Brown’s murder.
