A San Mateo County voter says she arrived to an empty and unlocked voting center on Sunday.
San Mateo County voter Madelyn Webster went to drop off her ballot at a voting center at Notre Dame de Namur University Sunday night.
The only issue was there was no one there.
"We also checked the front door thinking maybe they're taking a break in the front but that was locked. And then we called out again because there were restrooms there," Webster said.
Webster says she walked around the building for about 10 minutes trying to find someone before eventually leaving.
She tells us she arrived to the voting center around 6 p.m., about an hour after it had closed.
But, unaware of the operating hours, she thought it was still open since the doors were unlocked and a vote here banner was flying outside.

The incident prompted Webster to send an email to the county's chief elections officer.
The election's office says the voting center at NDNU is not one that's operated by the county.
They say every day at 5 o'clock their staff secures the voting machines and removes all ballots from the facility.
It's then up to the school staff to ensure the building is locked and secured.
The elections office was unavailable to go on camera Monday night but told ABC7 Eyewitness News in an email:
"The matter was reviewed by our Vote Center and supervisory staff and confirmed that all ballots, voting equipment, and election materials remained secure and were not compromised."

In addition to the county election's office, Webster also reached out to Supervisor David Canepa.
Canepa himself is on the ballot Tuesday- running for chief elections officer against the current assistant.
He says the regardless of who is responsible for keeping the facility locked, the incident raises unnecessary concerns.
"How did this happen? We need to understand how did this happen? And was this a one-off or has this happened before?" said Canepa.
The voting center was locked after hours Monday when ABC7 arrived to check.
Welcome news to Webster who says she just wanted to make sure everything was okay.
"I kept my ballot because I wanted to make sure it got into the right hands. So only after dinner did we drop it off at the Belmont police station," she said.
