HUNTSVILLE (April 3, 2014) Texas death row inmate Tommy Lynn Sells, 49, was executed Thursday evening in Huntsville for killing a teenage girl 15 years ago.
Sells was linked to more than a dozen slayings and claimed to have committed as many as 70 murders around the country.
He was convicted of slashing the throats of two girls in 1999 at their home near Del Rio.
Katy Harris, 13, was killed, but her 10-year-old friend survived.
Sells entered the girls’ home with the intention of sexually assaulting the older girl, whose throat was slashed and who was stabbed repeatedly, authorities said.
Sells called himself "Coast to Coast," a reference to where he says he's committed murders.
His attorneys were unsuccessful in convincing the U.S. Supreme Court earlier Thursday to halt the execution until the state released information about the source of the pentobarbital that was used in the lethal injection.
Earlier in the week a federal judge halted the execution, but the 5th U.S. Court of Appeals lifted the stay.
The inmate’s attorneys argued that the state should identify the source of the drug to ensure its quality and to protect Sells from unconstitutional pain and suffering, but Texas prison officials countered that the information must be kept secret to protect the provider from threats of violence.
