Cell-tower data being called out
Insurers’ use of location ‘pings’ to deny claims fought
HARTFORD, Conn. — It took Jaclyn Bentley nearly three years to prove she didn’t burn her house down for the insurance money, allegations she and her lawyer say were born of the junk practice of analyzing cellphone tower data.
She was camping with her husband and co-workers at least 17 miles from her Iowa home in May 2014 when it burned down, she says. An investigator for State Farm Fire and Casualty Co. said cell tower data showed Bentley’s phone was 5 to 12 miles from the campsite in the direction of her home just after the fire was reported — the suggestion being she could have been heading back to camp after starting the blaze.
Her claim was denied, and she was arrested on arson and insurance fraud charges. But she was acquitted after questioning State Farm’s analysis of the tower data, and she has sued the company for failing to pay her claim.
Despite acquittals like Bentley’s and expert testimony that cellphone tower data should not be used to pinpoint people’s locations, insurance companies continue to use the information to deny claims by casting doubt that customers were where they said they were. The problem, experts say, is that a cellphone can be up to 20 miles away when it “pings,” or connects with, a tower.
“I’ve gone through hell,” said Bentley, 37, of Clinton, Iowa, who cares for people with brain injuries and mental illness. “It’s ridiculous what happened. You’re innocent until proven guilty. I’ve never felt like I was treated like I was innocent.”
State Farm does not comment on pending litigation or specific claims, spokesman Justin Tomczak said.
“While I cannot comment on a specific claim, I can tell you that we rarely obtain phone said.
The records can be obtained only by a court order or a customer’s consent.
A private investigator, Tim Wilcox, chief executive of International Investigators Inc. in Indianapolis, said he believes cell tower data analysis can be fairly accurate in tracking someone’s movements, within a half-mile.
Michael Cherry, meanwhile, has testified in successful cases to free people who were imprisoned based in part on cell tower evidence. Among the early design team members of the Apollo 11 moon mission, Cherry is now chief executive of Cherry Biometrics, a computer and cellphone data analysis firm in Falls records,” he Church, Va.
Phones can be miles away when they ping towers, Cherry said, because a number of factors decide which tower handles a call, including which has the clearest signal and is the most cost-effective.
“They’re misinterpreting it, and it’s not very reliable to begin with,” said Cherry, who played no role in Bentley’s case.
Bentley, who spent three days in jail — including her birthday — after being arrested, said the insurance company claimed cellphones can be only up to 3 or 4 miles away when they ping towers. But she was able to disprove that claim with her cellphone records.
Hours after the fire was out and she had returned to the campground, she checked her voicemail and her phone pinged a tower near the campground. A few minutes later, her mother called her, and her phone pinged a tower back in Clinton, 17 miles away. Minutes later, her husband called her, and her phone pinged a tower about 20 miles away, she said.
A couple Cherry is helping, Monica and Ali Almazni of Perris, Calif., are facing trial on insurance fraud charges, stemming from the theft of their car in 2013. Their insurer, Progressive, said that before the car was reported stolen, the Almaznis’ cellphones pinged a tower near where the car was later found.
Cherry said the couple could have been where they said they were — Ali Almazni at a mall and his wife at home — based on the tower data.
Jeff Sibel, a spokesman for Progressive, said he would check into the Almaznis’ case, but did not follow up.
Another California couple, Linda and Eric Norwood, of Hemet, said they gave up on an insurance claim for their stolen pickup after State Farm used cell tower information to insinuate they were involved.
They said they couldn’t afford a lawyer to try to fight State Farm, and no criminal charges were filed against them.
Tomczak, the State Farm spokesman, declined to discuss the case.
