How Police Identified Him
Phoenix detectives built the case in a matter of days.

What He Told Detectives
A Phoenix police report released in 2025 detailed Teasley’s statements during his initial interrogation. Shown a photograph of Heike, he said, “That’s what I would want to look like, except a little bit more brown.” Shown surveillance footage of the suspect, he answered, “That’s me. I think, is it? I don’t know.”4AZ Family. Phoenix Police Report Details Interview With Suspect in Lauren Heike’s Murder
He told investigators he knew about Heike from the news but did not recall meeting her. Pressed for the truth, he asked, “What do you want me to do? Just give up my life?” and called the situation a “death sentence.” He denied planning any attack, saying he was “not the type of person to kill another person” and that if he had done something like that, “it definitely would not be premeditated.” During the same interview, Teasley disclosed in a written note to the officer that he was transgender.4AZ Family.

The Alleged Motive
Prosecutors allege Teasley killed Heike in a jealous rage tied to her appearance. Police say Teasley wrote diary entries in the days before the killing about his gender identity and sexuality: “I have been battling with my gender identity and sexuality… I am Christian, so this isn’t allowed.”7AOL/New York Post.

Prior Record and Background
Teasley had a substantial criminal record before the murder charge.

He was released from prison in November 2022, roughly five months before Heike’s death, and was still on probation at the time of the killing.11ABC15.

The Phoenix Officer Connection
An ABC15 investigation reported that a Phoenix patrol officer had an undisclosed personal relationship with Teasley. According to the police report, the two exchanged a large volume of messages up until the day of the arrest. After Teasley was taken into custody on May 4, 2023, the officer searched his phone for “Lauren Heike,” “Zion,” and “Teasley.” He later told squad mates he had a relationship with Teasley but had not reported it to his supervisor. The Phoenix Police Department investigated and suspended him for failing to disclose the connection. Investigators said the attack on Heike was still random, noting no prior communication between Heike and Teasley was ever found.6ABC15. New Report Details Lauren Heike Murder Investigation
