Officials with the maker of high-tech surveillance systems could not be reached for comment, and doors at its offices in a former Stokely Van Camp tomato cannery were locked yesterday.
A representative of property owner Revel Underwood Inc. said a maintenance worker called last week to say moving trucks had arrived to take away company equipment.
Revel Senior Vice President Rob Schick said the closing came as a surprise, and that he hasn't had contact with the company since the closing. "They had a great product," Schick said.
The firm as of last year had 43 employees and annual revenue of $8 million.
A former employee who asked not to be identified said in an e-mail that Chase bank called in a note and shut the business down.
Chase spokeswoman Nancy Norris said the bank doesn't comment on relationships with specific customers.
"In general, we try to work with our customers to create some kind of workout payment plan," Norris added. "When all else fails, we may choose to take possession of the collateral."
American Sentry was founded in 1999 by the father-son team of Jack and Jeff Brummett.
Banks, schools, casinos and other customers installed the surveillance equipment.
