Authorities light on details in arrest of San Marcos apartment fire suspect

During a Thursday morning press conference, authorities announced the arrest of a former Texas State undergrad accused of setting fire to a San Marcos apartment complex in 2018, a blaze that killed 5 people and injured another. Despite a flurry of media questions, local, state and federal agencies involved in the investigation offered little insight into a possible motive, what type of accelerant was used and what new details emerged that helped them move ahead on the cold case. "It was really predominantly based on the witness interviews we had at the time," San Marcos fire Marshall Jonathon Ferguson told reporters.
