The family of a San Antonio man who died while being booked into jail has filed a federal lawsuit against two Bexar County deputies, alleging the pair used unnecessary lethal force to restrain him. Emmanuel Mora, 37, died Aug. 27 while being booked at Bexar County’s Justice Intake and Assessment Annex. He was arrested by Balcones Heights police on drug charges and a parole violation, according to the lawsuit filed Friday in U.S. District Court in San Antonio.
