Port Arthur ISD music teacher killed in Harris County custody exchange

A Port Arthur ISD music teacher was shot to death during a custody exchange in northeast Harris County, turning a child handoff on Blue Timbers Court into a homicide that left students and coworkers mourning Marlon Sanders, 36.

Investigators said Sanders and his wife had gone to pick up a baby she shares with 38-year-old Gary Davis after a relationship that began while she and Sanders were separated. Court records said Davis texted the child’s mother that he was “on that type of time” and threatened not to give the child back. Just after midnight, Davis allegedly stepped outside in the 12700 block of Blue Timbers Court, near CE King Parkway and East Little York Road, and opened fire while Sanders stood by his vehicle in the street.

Harris County Precinct 3 deputies responded to the scene. Sanders was taken to a nearby hospital, where he later died. No one else was injured. Davis was arrested, charged with murder and booked into the Harris County Jail. His bond had not been set, and a motion was filed asking a judge to deny bond.

Port Arthur ISD described Sanders as much more than a classroom teacher. He worked as a music teacher at Adams Elementary School and coached Titans football and basketball, while also serving as a singer, DJ and musician. That mix of roles made him a familiar figure to students, families and colleagues in Port Arthur, where schools often depend on educators who carry their influence far beyond a single campus.

The killing also underscores how dangerous custody exchanges can become when relationships remain volatile. The Harris County Domestic Relations Office says it is a domestic-violence-informed agency and offers parenting-time services and supervised visitation, tools meant to reduce direct contact in high-conflict situations. The Harris County District Attorney’s Office says intimate-partner violence is among the most serious and dangerous crimes in the community and handles protective-order cases. The National Domestic Violence Hotline is available 24 hours a day at 1-800-799-SAFE (7233) or by texting START to 88788.

Texas advocates have warned that these cases are not rare. Families to Freedom says more than 200 people died from domestic violence in Texas last year, and it cites a 500% chance of death by firearm when a weapon is present in a domestic-violence relationship. In Harris County, Sanders’ death is a reminder that a routine exchange can become fatal when warning signs, access to guns and unresolved conflict collide.
