Cop in Sandra Bland Traffic Stop Now on Desk Duty Investigation continues into her suspicious death in Texas By John Johnson, Newser Staff Posted Jul 18, 2015 11:43 AM CDT 120 comments Comments This handout photo provided by the Waller County Sheriff’s Office shows Sandra Bland. (Waller County Sheriff’s Office, via AP) (Newser) – It sounds like Texas law-enforcement officials think the trooper who pulled over Sandra Bland was a little too aggressive. "We have identified violations of the department's procedures regarding traffic stops and the department's courtesy policy," says the Texas Department of Public Safety, without elaborating. The trooper has been placed on desk duty for the time being as the investigation continues into Bland's death, reports NBC News. Trooper Brian Encinia, 30, pulled Bland over because she failed to signal a lane change, and the DPS says she became combative during the stop, reports the San Antonio Express-News. The 28-year-old Chicago native was arrested on charges of assaulting an officer and was later found hanging in her cell. Though she had written of depression previously, her family doesn't believe she would have committed suicide. The jail, meanwhile, was lax in its policies, says the executive director of the Texas Commission on Jail Standards. “Inmates are required to be observed at least once every 60 minutes, and the Waller County Jail did not perform that observation as required,” says Brandon Wood. County officials say video of the arrest is now in the hands of the FBI and will be released soon.
