Mercedes Vega’s Accused Murderer Extradited to Arizona, Claims Bail Conditions Are ‘Unconstitutional’

PHOENIX — Sencere Patrick Hayes, 22, faces multiple serious charges, including first-degree murder, in connection to the brutal death of Mercedes Vega in April 2023. Recently extradited to Arizona, Hayes is now set to confront these allegations in court.

On November 8, 2023, a grand jury in Maricopa County indicted Hayes. Just days later, he was apprehended in his hometown of Chattanooga, Tennessee, where he had been in custody on separate charges. Officials anticipate further arrests in this ongoing investigation.

Court records detail additional charges against Hayes, including kidnapping, armed robbery, and auto theft. During his initial court appearance on Monday, Assistant Bureau Chief Kirsten Valenzuela emphasized the violent nature of the crime, describing it as resulting in “a horrific death.”

Vega was last seen on surveillance from her Tempe apartment prior to her disappearance. Investigators believe she was kidnapped shortly thereafter. A medical examiner’s report indicated she suffered blunt force trauma, gunshot wounds, and had bleach poured down her throat before being found in a burning vehicle off the I-10 freeway near Tonopah.

A 911 call from a passerby reported seeing the burning vehicle, but limited details were provided. Valenzuela requested that the court seal records related to Hayes’ case to protect the integrity of the ongoing investigation, which is being conducted by the Maricopa County Sheriff’s Office.

Vega’s parents, Erika and Tom Pillsbury, expressed mixed emotions regarding Hayes’ extradition. They were relieved that he was no longer a threat to the community but were taken aback by the timing of the news. They emphasized their resolve in seeking justice for their daughter and urged vigilance within the community as they advocate for Vega’s memory.

The presumed connection to a previous armed robbery involving Vega adds another layer of complexity to the ongoing investigation, though officials have not confirmed any direct links between the two cases.

During the court hearing, the state proposed a $2 million cash bond for Hayes, which he contested, labeling it “unconstitutional.” However, the judge upheld the bond requirement, reflecting the serious nature of the charges.

As the investigation continues, questions regarding motives and potential accomplices remain unanswered. Maricopa County Sheriff Russ Skinner commended law enforcement’s efforts, highlighting their commitment to achieving justice for Vega and her family. Hayes is scheduled to return to court on December 4.
