A man from Texas is facing accusations of murdering his girlfriend’s uncle after a dispute about infidelity led her to seek her uncle’s support.

Jaeveyin Porter, aged 21, has been charged with the murder of 36-year-old Miguel Garcia, as reported by the City of El Paso in a press release. The tragic event unfolded on a Sunday when the couple, along with their community, had returned from church.

Following the church service, the girlfriend went to pick up her uncle, bringing him to the apartment she shared with Porter, according to a report by local Fox affiliate KFOX. Investigators suggest that she sought her uncle’s intervention to persuade Porter to vacate the apartment after a heated argument over alleged cheating that started on Halloween.

Authorities stated that Garcia and the girlfriend informed Porter of their presence outside the apartment, but he refused to open the door. Eventually, when Garcia forced his way inside, the girlfriend recounted hearing multiple gunshots and witnessed Porter shooting at her uncle.

Law enforcement officers arrived at the La Estancia apartment complex on the 7900 block of Viscount Boulevard just before noon on Sunday. Upon arrival, they discovered Garcia’s lifeless body outside the apartment.

Officers searched the area and found Porter just about a block away.

Authorities began investigating the shooting and learned about the Halloween night argument that continued into Sunday. While speaking with police, Porter reportedly maintained that he was going to open the door to the apartment when Garcia left.

Investigators also spoke with multiple witnesses, with one of them saying they heard the girlfriend ask Porter why he shot her uncle, to which he responded, “I don’t give a f—” or “I don’t f— care,” per KFOX.

Porter was booked into the El Paso County Detention Facility.
