A young man from Texas, aged 23, faces allegations of concealing himself inside his former girlfriend’s house while she was away, and subsequently committing the murder of her new partner upon their return.

Authorities apprehended Shiateek De-Shean Wilson over the weekend, charging him with murder in connection to the death of 35-year-old Noel Denzel Miller, according to court documents.

In the early hours of Sunday, deputies from the Bexar County Sheriff’s Office responded to a shooting incident on Roveen Trail in Converse, roughly 265 miles southwest of Dallas. Upon arrival, emergency personnel discovered Miller lying on a bed upstairs, suffering from apparent multiple gunshot wounds, as reported by the San Antonio Express-News. He was declared deceased at the scene.

The woman involved, whose identity remains undisclosed, informed investigators that she and Miller returned home around 2 a.m. after an evening out. She headed to the bathroom for a shower while Miller went to the laundry room to gather clothes.

Shortly thereafter, she was startled by the sound of gunfire. Rushing to the bedroom, she discovered Miller wounded on the bed. In the doorway stood Wilson, identified as her ex-boyfriend, wielding a black handgun. Wilson allegedly remarked about her “playing games with him” before fleeing downstairs with her cellphone.

Desperately asking for her phone back to contact emergency services, Wilson reportedly tossed it back to her and cautioned her “not to tell on him,” as per the Express-News, referencing a probable cause affidavit. Wilson then escaped the premises on foot.

The woman said her ex likely fled to a friend’s house in the 800 block of Chesnut Manor, about a mile away from her home. Authorities located him at the address and took him into custody.

In an interview with detectives, Wilson allegedly admitted to shooting Miller, but asserted it was in self-defense, claiming Miller pointed a gun at him, San Antonio CBS affiliate KENS reported.

Per the report, Wilson said he got to his ex-girlfriend’s house at about 1 a.m., planning to “surprise” her with gifts of flowers, money, and cocaine. When he found she wasn’t home, he said he snuck in and hid in the closet to await her arrival. When she got home with Miller, Wilson said he tried to sneak back out of the home, but claimed Miller spotted him and pulled out a gun.

“[Wilson] stated that he only fired his weapon at [Miller] because [Miller] had pointed a gun at him, claiming he shot [Miller] in self-defense,” the affidavit reportedly states.

As he fled the scene, Wilson said he jumped over multiple fences and discarded the weapon. Inside the home, investigators said they found multiple fired cartridge casings and what appeared to be bullet holes.

Wilson is currently being held in the Bexar County Jail on $300,000 bond, records show. It was not immediately clear when he was scheduled to make his next court appearance.
