If you recall this story from a month ago, the good news and update is that the man suspected of starting the fire inside this Natomas Walmart has been arrested. According to Sac Fire, the fire was deliberately set, per video from surveillance cameras. The man could be seen spraying something on a clothing rack in the men's department then lighting it with a firework. Thanks to facial recognition software, the investigation has identified the suspect as 29-year-old Israel Huusfeldt. It took some time to track him down, but he was stopped Tuesday at a routine traffic stop in Placer County and was subsequently arrested. He will face arson charges.
