An attempt to serve an arrest warrant at a home in Claremont, California, turned into an eight-hour standoff on Tuesday, November 10, that drew a SWAT team, a bomb squad, a robot, a drone, helicopter surveillance, flash-bangs, tear gas and snipers on neighbouring roofs — and ended peacefully at about 7:30 p.m. when Elton John Cannon, 54, surrendered to San Bernardino County Sheriff's Department deputies outside his home in the 300 block of Utah Court, the Claremont Courier reported.

Deputies had arrived at the residence at 11:30 a.m. to serve both an arrest warrant and a search warrant, the Sheriff's Department said. Cannon barricaded himself inside the house rather than come out, and the operation that followed shut down the residential street for most of the day while tactical teams took up positions around the home and a mobile command center was set up nearby on Victoria Place.

Non-lethal rounds, tear gas — and an armored claw at the front door

Deputies kept their guns drawn throughout the encounter and fired non-lethal rounds at the front door in efforts to coax Cannon out of the residence, the Courier reported from the scene. Later in the day, armored assault vehicles were used to move officers into position and shield them from potential gunfire. One armored vehicle equipped with a claw removed a car from the driveway, a tree from the yard, the front door itself, and a portion of the garage door.

Witnesses reported that deputies also punched holes through the back and side of the house and tossed tear gas inside. Photographs taken after the surrender show the scale of the damage to the home. Neighbours told the Courier that Cannon's mother, who had also lived at the home, died last week — a detail deputies have not commented on, but one that hung over a street watching an already difficult week turn into a tactical operation.

A Mount Baldy car break-in started the case

The case stems from a reported vehicle burglary at Mount Baldy on October 3, in which, the Sheriff's Department said, a suspect broke the driver-side window of a locked vehicle and stole several items, including credit cards. "During the subsequent investigation, detectives identified 54-year-old Elton Cannon of Claremont, using one of the stolen credit cards to make purchases," the department's news release says. "Cannon also had multiple outstanding warrants from neighboring jurisdictions. An arrest warrant was authored for Cannon along with a search warrant for his residence." The purchases allegation is the department's account, and it has not yet been tested in court: Cannon is presumed innocent unless proven guilty.

The charges he was wanted on

Cannon was wanted in San Bernardino County on felony second-degree burglary and grand theft charges from the Mount Baldy investigation, and had five additional outstanding warrants, deputies said. The search warrant served alongside the arrest warrant was aimed at locating stolen property at the Utah Court home.

After surrendering, Cannon was transported to the West Valley Detention Center in Rancho Cucamonga, where he is being held ahead of a Friday appearance in Rancho Cucamonga Superior Court. Friday is November 13 — three days after the standoff — and that hearing is the next public step in the burglary and grand-theft case.

Deputies are asking for more victims to come forward

The Sheriff's Department released a photograph of Cannon and of his vehicle, a 2013 gray Honda CR-V, in an effort to identify additional victims — an indication investigators believe the Mount Baldy break-in may not have been the only one. Anyone with knowledge of additional criminal incidents or other pertinent information is asked to call the Sheriff's Fontana Station at (909) 356-6767. Anonymous tips can be made by phone at (844) 909-3006, by texting "REPORT," or online through the department's tip portal.

Claremont sits at the eastern edge of Los Angeles County, hard against the San Bernardino County line — which is why a San Bernardino County case, investigated from the Fontana station and charged in a Rancho Cucamonga courtroom, played out on a Claremont street. Utah Court is a residential block of single-family homes, and for most of Tuesday its residents watched snipers take positions on their neighbours' roofs while an armored vehicle dismantled the front of the house at the centre of it.

What happens next: Cannon's Friday court appearance in Rancho Cucamonga will set the course of the felony burglary and grand-theft case, and the five additional warrants will have to be answered as well. The Sheriff's Department's appeal for additional victims remains open, and the Utah Court house — its front door and part of its garage door removed, holes punched through its walls — is left as the physical record of how an October car break-in became an eight-hour tactical standoff in November.
