A Texas inmate scheduled to be executed Thursday evening has insisted he didn’t fatally run over his girlfriend in a jealous rage more than 18 years ago.
Daniel Acker was condemned for the March 2000 slaying of Marquetta George of Sulphur Springs. Prosecutors said he ran over George with his truck in rural northeast Texas because he believed she had been unfaithful to him.
Acker’s attorneys had asked the U.S. Supreme Court to stay his execution, arguing he is innocent of capital murder because his 32-year-old girlfriend’s fatal injuries were due to her decision to jump from his truck after he abducted her. A similar appeal was rejected earlier this month by the Texas Court of Criminal Appeals.
The high court denied, without comment, Acker’s appeal less than three hours before his scheduled execution.
The 46-year-old Acker would become the 18th convicted killer put to death this year in the U.S. and the 10th given a lethal injection in Texas, the nation’s busiest capital punishment state.
Acker would be the second Texas inmate put to death in as many days. Troy Clark was executed Wednesday for torturing and drowning an East Texas woman in his bathtub and then stuffing her body into a barrel. If Acker receives a lethal injection, it would be the first time in nearly six years that Texas has executed inmates on consecutive days.
At least eight other Texas inmates have execution dates in the coming months.
At Acker’s trial, several witnesses testified that he got into a heated argument with George at a Sulphur Springs nightclub the night before her death over his suspicions she was sleeping with another man. Authorities said that the next day, Acker forced George—kicking and screaming—into his pickup truck. A witness later saw Acker pull George’s body from his truck and lay her on the ground.
In a petition to the Supreme Court, Acker’s attorney, Richard Ellis, argues the conviction was based on what he describes as a “now discredited” theory that Acker strangled George while he was driving.
Ellis said prosecutors changed their theory of George’s death after a prosecution expert testified at a post-conviction hearing in 2011 that she died from injuries after being run over.
At Acker’s trial, a medical examiner testified George had extensive injuries all over her body and her neck injuries were consistent with strangulation. But the medical examiner could not determine if strangulation or blunt force caused George’s death. The autopsy report did conclude that several of George’s injuries could have resulted from “an impact with or being ejected from a motor vehicle.”
“From the moment Daniel turned himself into the authorities, he said that the victim … jumped from the truck,” Ellis said. “He has taken full responsibility for abducting her and has shown great remorse for that.”
In its response to Acker’s Supreme Court petition, the Texas attorney general’s office argued the theory that Acker ran over his girlfriend was presented at the trial to jurors.
“Acker produces no new evidence showing he did not commit the crime but continues to assert that George’s death resulted from her leap from the vehicle—a theory rejected by the jury at the time of trial,” the attorney general’s office said.
Multiple witnesses testified at Acker’s trial that he made several death threats against George in the hours before her death.
In a 2017 ruling, the 5th U.S. Circuit Court of Appeals said the prosecution’s theory of George’s death was “largely based on strangulation.” But in denying Acker’s appeal, the 5th Circuit ruled that all of the evidence, including the updated cause of death, still supports the prosecution’s case as it was presented in the indictment and at trial.
