McKinney man says Collin County manipulated $50 million jail lawsuit
A McKinney plaintiff says Collin County skewed his $50 million jail case, even as a judge sanctioned him and declared him a vexatious litigant.

A Collin County district judge sanctioned McKinney plaintiff Jacob Luce and declared him a vexatious litigant in a $50 million lawsuit tied to a 2022 jail-cell extraction. Luce says the county manipulated the proceedings in a case he traces to a July 8, 2022 incident at the jail, where he alleges he suffered spinal trauma in a violent, unprovoked extraction captured on HD video.
The order, titled Order of Sanctions and Declaring Jacob Luce a Vexatious Litigant, was filed June 16, 2026 at 2:31 p.m. in Cause No. 471-04058-2024 in the 471st Judicial District Court. It says a hearing was held that same day, that Collin County’s motion for sanctions and supplemental motion were granted, and that the court found violations of Texas Rule of Civil Procedure 13, Chapters 10 and 11 of the Texas Civil Practice & Remedies Code, and the court’s inherent authority.

Related original proceedings in the Fifth Court of Appeals are dated Feb. 23, 2026, April 17, 2026 and April 28, 2026. A May 5, 2026 memorandum opinion involved Jacob C. Luce.

The Collin County Medical Examiner ruled the death a homicide, and the sheriff said seven detention officers were fired and one resigned after an internal investigation.
Collin County released about 40 minutes of jail surveillance video on July 9, 2021. Scott’s family and attorney Lee Merritt demanded arrests and accountability after viewing nearly five hours of footage, and the released video was edited and had no audio because the camera system did not record sound.
