A 23-year-old man from Texas is facing charges after allegedly concealing himself in his ex-girlfriend’s home and fatally shooting her new boyfriend upon their return. The suspect, Shiateek De-Shean Wilson, was arrested over the weekend and charged with murder in connection with the death of 35-year-old Noel Denzel Miller, according to court documents.

The incident unfolded early Sunday morning, when deputies from the Bexar County Sheriff’s Office responded to reports of a shooting at a residence on the 7300 block of Roveen Trail in Converse, located approximately 265 miles southwest of Dallas. Upon arrival, first responders discovered Miller in an upstairs bedroom, suffering from multiple gunshot wounds. Sadly, he was pronounced dead at the scene, as reported by the San Antonio Express-News.

According to investigators, the victim’s girlfriend, whose identity remains undisclosed, recounted that she and Miller had spent the evening out and returned home around 2 a.m. on Sunday. While she went to the bathroom to shower, Miller headed to the laundry room to gather some clothes.

Moments later, the woman was alarmed by the sound of gunfire. Rushing into the bedroom, she found Miller injured on the bed and Wilson, whom she recognized as her ex-boyfriend, standing in the doorway with a black handgun. Wilson allegedly accused her of “playing games with him” before fleeing the scene with her cellphone.

A short while later, the woman said she was startled by the sound of several gunshots. She ran into the bedroom and found the injured Miller on the bed. In the doorway, she saw Wilson, whom she identified as her ex-boyfriend, holding a black handgun. Wilson reportedly said something about the woman “playing games with him,” before taking off downstairs with her cellphone.

As the woman pleaded for Wilson to return the phone so she could call 911, he allegedly threw her phone back upstairs and “told her ‘not to tell on him,’” the Express-News reported, citing a probable cause affidavit. Wilson then fled the home 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.
