The man accused of chasing down and fatally stabbing jogger Lauren Heike on a north Phoenix desert trail pleaded guilty to first-degree murder in court Friday, a plea deal that will likely allow him to avoid the death penalty. The guilty plea comes more than three years after the April 2023 killing that terrified hikers across the Reach 11 Recreation Area.
According to Arizona's Family, court records show Teasley entered his guilty plea Friday, and a judge has scheduled his sentencing for December 4. Heike, 29, was found stabbed more than a dozen times on the Reach 11 trail near 64th Street and Mayo Boulevard on April 28, 2023, according to KTAR News. Court documents cited by the station report she was stabbed 15 times after her attacker chased her down; police believed she fought off the assault and tried to escape, but her injuries proved too severe.
DNA and Cellphone Data Led Police to a Suspect
Investigators linked Teasley to the killing through DNA found on Heike's shoe, combined with cellphone location data that placed him near the scene, per the same account from Arizona's Family. Phoenix police arrested him on May 4, 2023, at an apartment complex roughly 1.5 miles from the stretch of trail where Heike was attacked, according to FOX 10 Phoenix, which explained how he could have reached the remote desert corridor on foot.
During interrogation after his arrest, Teasley confirmed his own identity when detectives showed him trail surveillance footage of a man fleeing the scene, telling them simply, “That's me,” according to Court TV. Phoenix Police Department homicide investigators concluded the ambush was a random attack, finding no evidence that Teasley and Heike knew each other before the encounter on the trail.
A Violent History That Predated the Killing
Teasley had been free for only about five months when Heike was killed. He was released from an Arizona prison in November 2022 after serving time. His case involved seven thefts; he later pleaded guilty to armed robbery, disorderly conduct and robbery, with ten charges dropped. He was on probation at the time of the trail attack.
That history prompted Maricopa County Attorney Rachel Mitchell to announce a formal review in May 2023 of how prosecutors had handled Teasley's earlier violent charges, examining whether systemic changes were needed in how repeat offenders are managed. Police probable cause documents released around the same time indicated Teasley had also been terminated from his job shortly before the murder over aggressive conduct toward female co-workers, raising questions about warning signs investigators later scrutinized.
Death Penalty Notice Preceded the Plea Deal
Prosecutors with the Maricopa County Attorney's Office had filed a formal Notice of Intent to Seek the Death Penalty against Teasley in January 2024, well before Friday's plea deal was finalized, KTAR News reported. Heike's family had supported the county attorney's decision to pursue capital punishment, according to the outlet.
Teasley also did not complete basic training, Court TV reported.
Separate Child Exploitation Case Adds to Sentencing
Beyond the murder case, Teasley was indicted on 10 counts in 2025 after investigators found he possessed sexually explicit images involving a child under 15 years old. He pleaded guilty to one count of sexual exploitation of a minor in that case, and sentencing in that matter is also scheduled for December 4, the same date set for his murder sentencing.
