Mark Gideon was arrested around 6:20pm yesterday near the intersection of Herald Avenue and McCarty Drive in east Houston.
Gideon is accused of killing his sister, 52-year-old Vonda Gideon, and their 75-year-old mother, Margaret Gideon, at a home in the 9200 block of Kirkleigh Lane in northwest Houston. Officials believe the victims had been dead for several days before a concerned neighbor called authorities on Thursday and asked them to perform a welfare check. Both appeared to have suffered some type of head trauma.
Vonda's car white Honda Ridgeline was stolen from the scene but later recovered in east Houston hours later.
Authorities say a tip helped them find and nab Gideon. According to a Harris County Sheriff's Office statement, he provided investigators with "a complete statement regarding the deaths of his mother and sister."
Gideon, 54, is being held without bond at the Harris County Jail on two capital murder charges. A Harris County court clerk read the charges against him around 2am, but he wasn't there to hear them. According to officials, he didn't show up in court because of a medical issue. No additional details have been released.
