Texas Father Charged with Capital Murder, 2-Month-Old Dies with Brain Bleed and Skull Fracture

The parents of a 2-month-old Texas baby are facing charges after police say the infant died from physical abuse.

According to Fox 26 Houston, Demari Ossain Alston, 27, is facing a capital murder charge, while his girlfriend, 22-year-old Trinity Nyomi Perez, is facing one felony count of injury to a child.

Their son, Zayn Alston, passed away from blunt force injuries on September 11, 2024.

Court records indicated that on September 9, 2024, an investigation began after Zayn had been treated at two different emergency rooms for injuries. Police then arrived at the Memorial Hermann Hospital in Houston, following a report concerning the infant’s skull fracture, retinal hemorrhaging, and brain bleed.

During an interview with investigators, both defendants gave voluntary statements, according to Law&Crime, with Alston allegedly claiming he thought Zayn had an “allergic reaction.”

“Alston said he is the last person to see [Zayn] alive,” the affidavit read. “When asked why his son was brought to the hospital last night, your Affiant observed Mr. Alston say, ‘This s— is crazy. I am not going to lie.’”

“Mr. Alston said [Zayn] may be having an allergic reaction causing everything to swell because [Zayn] had not ever had problems breathing.”

Perez allegedly claimed she was in the living room in a Houston apartment when Alston, who was alone with the infant in a bedroom, said that he tripped on a shoe while holding him.

During a search of Alston’s phone, investigators uncovered numerous incriminating search queries, including, in part:

• Will you go to jail if you find your child unresponsive
• my 2-month-old died is anyone getting charged
• best Houston defense lawyers child abuse cases

Court records stated that the infant had also been injured in July 2024, when he was 10 days old, with fractures to his arm, clavicle and ribs.
