A 47-year-old San Antonio man has been arrested and charged with arson, burglary, and criminal mischief in connection with a house fire last year at the home of his wife's ex-husband. Authorities say surveillance footage and other evidence links Kinney to the incident, which occurred while the homeowners were on vacation in Hawaii. Kinney has denied any involvement in the alleged attack.

Why it matters

This case highlights the potential dangers of domestic disputes escalating to violent acts, as well as the challenges law enforcement faces in investigating complex cases involving circumstantial evidence. The alleged arson attack also raises concerns about home security and the vulnerability of properties when owners are away.

The details

According to the investigation, on July 31, 2025, a fire was reported at a home in far west Bexar County, causing an estimated $500,000 in damage. Authorities found evidence of forced entry, a cut power line, and a strong gasoline odor, leading them to suspect arson. Surveillance footage showed a vehicle matching Kinney's driving away from the scene shortly before the fire was reported. Investigators also traced the purchase of gas cans used in the alleged attack to Kinney based on video evidence and receipts.

  • On July 27, 2025, Kinney allegedly purchased the gas cans used in the fire at a Walmart near his home.
  • The house fire was reported just before 3:30 a.m. on July 31, 2025.
  • Kinney was arrested by the Bexar County Sheriff's Office on March 10, 2026.
