Logan Pierson, an 8-month-old infant, died on July 12, 2022, in Odessa, Texas. On the evening of July 9, his father Kameron Gammage (23) smoked marijuana and then attempted to play with the crying baby by tossing him in the air. Gammage, who admitted to being frustrated by the infant's crying, claimed he "accidentally" dropped the baby on approximately the fourth toss, causing the infant to hit the floor hard and sustain heavy bruising and swelling to the left side of his face and head. Gammage did not tell the baby's mother, Leyla Pierson (18), what happened, instead claiming the baby hit his head on the crib. Neither parent sought medical attention over the following three days, despite the visible injuries and the baby becoming increasingly fussy. On the morning of July 12, Pierson found the baby unresponsive and not breathing. Gammage was initially charged with injury to a child causing serious bodily injury, which was later upgraded to capital murder. Pierson was charged with injury to a child by criminal negligence for failing to seek medical care.
Contexts/Conditions
Is there any mention of child drug ingestion or overdose?
Is there any mention of a drowning incident (either intentional or accidental)?
Is there any mention of a firearm incident?
Is there any mention of inappropriate supervision (e.g., child wandered off and drowned)?
Is there any mention of inflicted injury? (e.g. slapped, punched, kicked, choked)
The Odessa Police Department affidavit (Document 4) states that Kameron Gammage "began tossing the infant in the air then catching him. Kameron reported he was frustrated, and the infant would not stop crying. Kameron claimed he 'accidentally' dropped the infant after about the 4th toss, which caused the infant to land on his left side. Kameron reported the infant hit the floor 'hard' when he landed." The infant sustained "heavy bruising swelling to the left side of his face and head" and "multiple smaller bruises along the top of the deceased infant's cranium." The use of quotes around "accidentally" in the official affidavit and the subsequent upgrade to capital murder (Document 3) strongly indicate this was inflicted injury.
Is there any mention of malnutrition, starvation, or dehydration?
Is there any mention of medical neglect?
Multiple documents describe the parents' failure to seek medical attention for the infant for three days after visible bruising and swelling appeared. The Odessa Police Department affidavit (Document 4) states: "Due to Kameron Gammage causing serious bodily to an infant and intentionally neglecting to seek medical attention for the infant for 3 days." Additionally, Document 4 states regarding Pierson: "Due to Leyla Pierson knowing about the bodily injury to her 8-month-old infant and neglecting to seek medical attention for the infant for 3 days." The news article (Document 2) corroborates: "Pierson told investigators she noticed the bruising on July 9 but didn't seek medical care for the child."
Is there any mention of a motor vehicle crash or incident?
Is there any mention of a murder-suicide incident?
Is there any mention of outdoor elements (including hot car deaths)?
Is there any mention of prenatal substance exposure (including fetal alcohol syndrome or neonatal abstinence syndrome)?
Is there any mention of sexual abuse?
Is there any specific mention of shaken baby or abusive head trauma?
While the specific terms "shaken baby" or "abusive head trauma" are not used, the infant sustained significant head injuries from being thrown in the air and dropped by his father. The Odessa Police Department affidavit (Document 4) describes "heavy bruising swelling to the left side of his face and head" and "multiple smaller bruises along the top of the deceased infant's cranium." These injuries to the head, caused by the father's abusive conduct (tossing and dropping the infant while frustrated), constitute abusive head trauma.
Is there any mention of prolonged abuse or torture (including restraints, captivity)?
Is there any mention of an unsafe sleeping environment?
Individuals Involved
Was an adoptive parent or guardian involved in the death?
Was a biological father involved in the death?
Kameron Gammage is consistently identified as the infant's father across all documents. The news article (Document 2) states "his 8-month-old son, Logan Pierson." The Odessa Police Department affidavit (Document 4) identifies him as "the father" and states he tossed and dropped the infant, causing fatal injuries. His charge was upgraded to capital murder (Documents 2 and 3).
Was a biological mother involved in the death?
Leyla Pierson is identified as the infant's biological mother. She was charged with "Injury to a Child, Elderly Individual, Or Disabled Individual / Criminal Negligence" (Document 4) because she "knowing about the bodily injury to her 8-month-old infant" and "neglecting to seek medical attention for the infant for 3 days, to which the infant was found deceased 3 days later."
Was a day care worker, babysitter, or nanny involved in the death?
Was a female paramour or friend involved in the death (e.g., girlfriend, stepmother)?
Was a foster parent involved in the death?
Was a male paramour or friend involved in the death (e.g., boyfriend, stepfather)?

Parent/Caregiver Factors
Was an adult charged or arrested for the child's death?
Both parents were arrested and charged. The Odessa Police Department affidavit (Document 4) states Kameron Gammage was arrested for "Injury to a Child, Elderly Individual, Or Disabled Individual Causing Serious Bodily Injury" and Leyla Pierson was arrested for "Injury to a Child, Elderly Individual, Or Disabled Individual / Criminal Negligence." The news articles (Documents 2 and 3) report that Gammage's charge was subsequently upgraded to capital murder.
Is domestic violence by the parent/caregiver referenced?
Is there any mention that the death occurred in a temporary shelter or while homeless?
Is an intellectual disability of the parent/caregiver referenced?
Is the mental health of the parent/caregiver referenced?
The Odessa Police Department affidavit (Document 4) states: "he admitted that he does have extreme anger issues and has been dealing with a lot of stress lately, including the infant frequently crying." While no formal mental health diagnosis is mentioned, the repeated references to "extreme anger issues" across multiple documents indicate behavioral/mental health concerns. This is further evidenced by his admission to strangling two dogs to death, which suggests significant behavioral disturbance.
Is a history of arrests or criminal charges for the parent/caregiver referenced?
The CBS7 news article (Document 3) reports that Gammage had a separate prior criminal matter: "The Andrews Police Department tells CBS7 that they opened an investigation for an offense of sexual assault of a child where Gammage was the suspect. The case was presented to an Andrews County Grand Jury and Gammage was indicted on May 19, 2022, for the offense of sexual assault of a child. A warrant for Gammage's arrest was issued... Investigation revealed the initial offense occurred between 2019 and 2020. The victim was 15 at time of the original offense." This indictment predates Logan's death in July 2022 and involves a different victim.
Is substance use by the parent/caregiver referenced?
Both parents admitted to smoking marijuana. The Odessa Police Department affidavit (Document 4) states: "Kameron further admitted that he frequently smokes marijuana to help him stay calm. Kameron reported that on Saturday (7-9-22), he and Leyla had smoked marijuana." Document 2 corroborates: "Gammage told investigators on July 9, he smoked marijuana."
Notable Details
Several notable details emerge from the source texts. First, Gammage admitted to strangling two dogs to death and attempting to dispose of their bodies, which the CBS7 article (Document 3) and the police affidavit (Document 4) both document: "Kameron admitted that he has recently strangled two dogs to death and attempted to dispose of their bodies to avoid getting in trouble." This animal cruelty is a recognized risk factor for violence against humans. Second, Gammage had already been indicted on May 19, 2022 for sexual assault of a child (a different victim, aged 15, offense occurring in 2019-2020) before Logan's death in July 2022 (Document 3). Third, the mother Leyla Pierson was born on April 8, 2004 (Document 4), making her only 18 at the time of Logan's death and approximately 16-17 when she became pregnant. Fourth, both parents admitted to attempting to clean the apartment (which contained dog feces on the floor) before law enforcement arrived (Document 4).
