A Denver resident claims she was mistakenly accused of theft after authorities used Flock cameras to trace her vehicle.

While the tracking technology has sparked privacy debates, it has garnered approval from law enforcement for its role in apprehending suspects.

The police chief in Columbine Valley later dismissed the summons issued against her. However, the woman contends she should never have been implicated, asserting that her vehicle was not present at the location where the alleged package theft occurred.

On September 27, Chrisanna Elser found herself facing a court summons when an officer from the Columbine Valley police force arrived at her residence. She was accused of stealing a $25 parcel in Bow Mar. The officer claimed he possessed doorbell footage of the incident and confirmed her car’s presence in the vicinity via Flock cameras.

“The evidence is definitive. I would not be here unless I was absolutely certain,” Sgt. Jamie Milliman assured Elser at her doorstep.

The only problem, Elser says, is that she wasn’t there, and she had evidence to prove it. She gathered dash camera footage from her car, a Google Maps location log, and doorbell video showing her walking into her tailor’s house at the time the package was stolen.

“He just kept telling me that any evidence I had wasn’t worth it,” Elser said.

In one exchange, Milliman declined to let Elser see the doorbell footage of the theft after she denied stealing the package.

“You have not been honest with me, so I’m not going to extend you any courtesy of showing you a video when I don’t need to,” he told her.

Several weeks later, Elser was able to get in touch with Columbine Valley Police Chief Bret Cottrell, who reviewed her evidence and voided the summons.

In an email to Elser, Cottrell wrote, “After reviewing the evidence you have provided (nicely done, btw), we have voided the summons that was issued.”

Elser argues she shouldn’t have needed to prove her innocence and worries that Flock cameras could be used too aggressively by police.

“They need to be used properly and with caution,” she said. “There needs to be a conversation, not a rush to accuse anybody and everybody.”

FOX31 reached out to the Columbine Valley police chief but has not heard back.

Now, Elser is urging her neighbors to collect their own digital evidence, in case they ever need it.
