A Fort Worth mother faces manslaughter charges after her 1-month-old son died from methamphetamine exposure last summer.
Swanietra Cooke, 36, was arrested on Tuesday following a months-long investigation.
Zachariah Gianni Cooke died in July 2025 from what medical examiners ruled a homicide.
The Tarrant County Medical Examiner’s Office determined methamphetamine toxicity caused the infant’s death.
Investigators discovered drug paraphernalia feet from the baby’s crib.
Court documents reveal a troubling pattern of substance abuse in the household. Cooke admitted to using methamphetamine for approximately one year before her son’s death.
The baby had previously been removed from Cooke’s custody. He was born with methamphetamines in his system, according to the arrest warrant affidavit.
The infant’s father told investigators he and Cooke would “get together to use drugs, methamphetamine, and have consensual sex.” A second child reported Cooke routinely smoked inside the home, per Fox 4 KDFW.
Police found two glass pipes on a side table near the crib and Cooke’s bed. The pipes are commonly used for smoking methamphetamine.
Drug tests administered to Cooke after her son’s death came back positive.
The arrest warrant states investigators believe she recklessly committed the offense of manslaughter, Fox 4 reported.
Tarrant County inmate records show that Cooke is also facing charges for theft of property valued at more than $2,500, burglary of a building, mail theft, and making false statements to law enforcement.
Cooke remains in the Tarrant County jail.
