Man apparently committed suicide; civil rights group wants 'thorough' inquiry in HPD Central Jail's policies According to Harris County criminal records, Hung Do, 38, was sentenced to two years deferred adjudication in September 2014 for possessing less than a gram of cocaine. Houston police and the Harris County District Attorney's Office are investigating his death, but the Texas Civil Rights Project says that isn't enough. David James, a staff attorney with the group's Houston office, said the government has specific responsibilities when they place someone in custody. HPD officials said Do went through a medical and mental health screening, conducted by the Houston Health Department, before he was booked into the jail.
