The body of a Texas teenager was found in the trunk of an abandoned burning car. Now, two decades later, the case remains unsolved.

On Sept. 18, 2001, the Texas Department of Public Safety says the Texas Rangers and the Anderson County Sheriff’s Office began an investigation after human remains were found in the trunk of an abandoned burning car in Anderson County.

Officials said they identified the remains as Joshua Seales and an autopsy revealed the death was ruled a homicide.

Investigators have said the last 24 hours of his life is a mystery. Seales went to a bank and made a small withdrawal. At the time, witnesses said a well-mannered black man was with Seales, but no one has a clue who that man was, according to KLTV.

Employees of the bank gave enough of a description where a composite sketch was drawn, but has not lead anywhere.

Anderson County Sheriff Greg Taylor told KLTV in 2006, “That’s the only lead we have — that he was with this black male. We don’t know if this black male is related to the man, or a friend.”

After the bank, Seales went to a nearby restaurant and bought a large amount of food, officers said.

Police said they received a call the next day stating a Buick was set on fire in the country. From crime scene photos, officials said that someone used a flammable liquid to light the car on fire from a distance. The car belonged to Seales’ girlfriend, who allowed him to drive it.

Tips started to come in at the time, which witnesses said the day before the body was found there was apparently an argument between Seales and some other men not far from the crime scene.

Investigators have stated who those people were and why they were arguing with Seales are still unknown.

The case remains open and the Texas Crime Stoppers is offering a cash reward of up to $3,000 for anyone who provides information that leads to an arrest. Anyone with information is asked to call (800) 252-TIPS (8477).
