Sonoma police have arrested a man suspected of lighting one of two suspicious fires that burned near Depot Park and the Mission San Francisco Solano in Sonoma early Wednesday morning.A replica of a mission-era outbuilding located at the rear of the state-owned Mission, also known as the Sonoma Mission, at 114 East Spain St., burned at about 6 a.m., Sonoma Police Chief Bret Sackett said.The Sonoma Valley Fire & Rescue Authority had responded to a Dumpster fire in nearby Depot Park at 270 First St. West at about 4 a.m. Investigators considered the Mission fire suspicious because of its proximity to the Dumpster fire, Sackett said.The person who reported the Dumpster fire to the fire authority saw two men with backpacks standing next to the burning Dumpster, Sackett said. The men fled when firefighters arrived, the witness said.Shortly after the 4 a.m. Dumpster fire,Sonoma police responded to a report of someone knocking over trashcans near the Sonoma Plaza, Sackett said. Police found and detained a man who matched the description of one of the men seen near the burning Dumpster, Sackett said. The witness identified the detained man as one of the two men seen near the Dumpster fire and police found a butane lighter and matches in the man’s backpack, Sackett said.Police then arrested 27-year-old Travis Smith for arson. He was booked into the Sonoma County jail.Cal Fire is investigating the fire at the Sonoma Mission and the Sonoma County Sheriff’s Department, which provides police services to the City of Sonoma, is investigating the Dumpster fire.
