The city's economic development manager has quit after being on the job less than a year.

Debbie Chandler, who was hired last May to spur business development through the city's newly created Office of Economic Initiatives, submitted her resignation to City Manager Richard Miranda earlier this week.

In her four-sentence letter, Chandler didn't offer an explanation as to why she was leaving her position, stating only that she was "grateful for the opportunity to further the efforts of economic expansion for Tucson."

Chandler did not return calls from the Arizona Daily Star.

Also leaving Miranda's economic team at the end of December is Economic Development Specialist Jennifer Hackman, who is relocating to the Chicago area, according to a city memo issued by Miranda.

For the moment, Hackman's responsibilities will be taken over by the recently hired management intern for economic development.

Miranda said Camila Martins-Bekat, who has a master's degree from the University of Denver in global finance, trade and economic integration, will work on business incentives, downtown issues and more.

While the management intern position pays around $35,000 a year with no benefits, Economic Initiatives Program Director Chris Kaselemis said there's always the possibility of moving up the ladder.

"Camila has a great education, and with her studies in economic development I expect her to provide immediate assistance to our office," Kaselemis wrote in an email. "If she proves herself, as I expect she will, there will most likely be an opportunity for her to obtain a permanent position."
