HUNTSVILLE, Texas (AP) - The Latest on the execution of a Texas inmate convicted in the 1998 killing of a suburban Houston community college student (all times local):

12:20 p.m.

Attorneys for a Texas death row inmate who maintains his innocence and contends his murder conviction was based on junk science are asking the U.S. Supreme Court to stop his execution.

Larry Swearingen is set to receive a lethal injection Wednesday evening for the 1998 killing of 19-year-old Melissa Trotter. Her body was found about a month after she was seen leaving her suburban Houston college.

Swearingen's attorneys allege in their Supreme Court petition prosecutors used "false and misleading testimony" related to blood evidence and a piece of pantyhose used to strangle Trotter.

The 5th U.S. Circuit Court of Appeals last week rejected a challenge to the testimony, saying it would not have many any difference in the trial due to the "mountain of inculpatory evidence" against Swearingen.

A Texas death row inmate who has long maintained his innocence is facing execution for the abduction, rape and murder of a suburban Houston community college student more than 20 years ago.

Larry Swearingen is set to receive a lethal injection Wednesday evening for the December 1998 killing of 19-year-old Melissa Trotter. Her body was found nearly a month after she was last seen leaving the college in Conroe.

Swearingen's attorneys plan to ask the U.S. Supreme Court to halt the execution, arguing that lower courts haven't taken into account "the considerable amount of evidence of innocence."

Prosecutors say Swearingen has a history of violence against women and they stand behind the "mountain of evidence" used to convict him in 2000.
