"The suspect has been identified as 18-year-old Darriynn Brown," the Dallas Police Department said in a news release. "He is charged with kidnapping and burglary. Dallas investigators anticipate additional charges, pending results from a forensic analysis." According to an arrest affidavit obtained by WFAA-TV, Cash was sleeping in the home Saturday morning when Brown allegedly broke in and kidnapped him. Hours later Cash was found dead, just blocks from his home. There were video surveillance cameras inside the home that allegedly filmed the kidnapping. According to a press release on Monday, the boy's biological mother, Melinda Seagroves, had been trying to find her children since the dad allegedly took them earlier this year. Cash's twin brother has since been reunited with Seagroves, police say. Brown remains in the Dallas County jail on a $750,000 bond, according to online jail records, which do not list an attorney who might speak on his behalf. He has not yet entered a plea.
