HOUSTON --We have new information about a body found in a large trash bin in Fort Bend County. The victim is an 18-year-old who recently graduated from high school, but investigators say the biggest unanswered question is how the victim died. The disturbing discovery was made Tuesday night around 10:15pm at the Preserve at Colony Lakes apartments on Farrah Lane near Colony Lake Estates between Stafford and Sugar Land. Throughout the afternoon, family members showed up at the apartment where authorities say Seantrell Davon Marshall, 18, lived with his mother and stepfather. Marshall's death was a horrible shock to his family. "We're taking it pretty hard. He just graduated from high school and then to find out something like this happened, it's kinda hard on us," said Joe Naulings, the victim's uncle. Marshall's body was found inside a trash dumpster not far from his apartment on Tuesday night. Authorities with the Fort Bend County Sheriff's Office say a neighbor reported a fire behind the large trash container, then saw a nude body inside. Investigators believe clothing belonging to the victim was burning in a pile behind the trash bin. "I think that's highly unusual. Typically if someone is going to leave someone nude they don't have their clothes there to begin with. It's very odd that they burned the clothes. More than likely that's an attempt to conceal some type of evidence that may be on the clothes," said Chief Craig Brady of the Ft. Bend Co. Sheriff's Office. Chief Brady also says there were no obvious signs of trauma on the body. While authorities try to find out how Marshall died, his family focuses on what they remember best about the 18-year-old young man who just graduated from Ft. Bend Dulles High School. "A real nice person. He was outgoing, you know, but real nice person. He got along with everybody so we don't know what could have happened or what's going on and that's what we're trying to find out now," said Naulings. The Galveston County Medical Examiner's Office is performing an autopsy to determine the cause of death. So far, there have not been any arrests made in this case.
