In the 1960s, 70s and early 80s, another U.S. 59 area, San Jacinto County, became the focus of an investigation of the arrests of motorists. According to news reports and to later court testimony, San Jacinto County sheriff's officers were making arrests of "long-haired" men and the occupants of their vehicles. The officers looked for "longhairs" driving cars with bumper stickers for Houston radio station K-101. The arrests were made on various pretenses, usually some traffic violation, but the vehicles were searched and if any amount of drugs or drug paraphernalia were found, then officers confiscated cash and other valuables and more often than not released the arrested parties.
San Jacinto Count y Sheriff James C. "Humpy" Parker and four of his officers were arrested and tried in 1983 for offenses related to those "traffic stops." The sheriff and his men were convicted of, among other charges, using a torture similar to waterboarding to get confessions. They would put a damp wash cloth or towel over a "suspect's" face and pour water onto it.
Parker pleaded guilty and served 10 years in prison. He died of cancer in 1999.
