Lawrence Mayor Jeremy Farmer looks to the crowd at a City Commission meeting, April 14, 2015, at City Hall.

Jeremy Farmer — whose whereabouts have been unknown since he resigned as Lawrence’s mayor more than three months ago — appeared earlier this week at a deposition in St. Joseph, Mo.

Farmer, said to be dating Amanda Comeau, was subpoenaed for a motion to modify child custody between Comeau and her ex-husband, Tad Binder, according to electronic filings on Missouri’s Office of State Courts Administrator’s website.

Comeau is the woman for whom Farmer paid a portion of an airline ticket in July using a city-issued credit card.

A credit card reconciliation statement provided by the city lists a charge of $103 to Southwest Airlines on July 23. The ticket confirmation lists Amanda Binder as the passenger. She traveled from Washington, D.C., to Kansas City the same day as Farmer, who was there to attend a conference hosted by the Young Elected Officials Network.

Interim City Manager Diane Stoddard told the Journal-World in August that it appeared Binder — now Comeau — had originally paid for the ticket, but when a flight needed to be changed, Farmer used the city credit card to pay for the additional charges.

The $103 charge was part of the approximately $1,100 in personal expenses Farmer racked up on the city’s credit card. Most of the charges occurred in July during two trips to Washington, D.C.

Farmer repaid the city before resigning as mayor Aug. 12.

At the time, he wrote a memo to city staff and commissioners explaining that he used the city’s card to pay for personal expenses because his personal credit cards had been “compromised.”

Attorney Michelle Carpenter, who is representing Comeau’s ex-husband, said Comeau and Farmer have denied living together. Comeau’s address is listed on electronic court documents as a residence in St. Joseph. Farmer is not a defendant in the case, but rather has been called as a witness in the custody matter.

Carpenter said that during the deposition, when asked about his current employment, Farmer said he was doing consulting for businesses in Kansas City.

The Journal-World has requested a copy of Farmer’s full deposition.

Up to now, it was unclear where Farmer went after his resignation. He hasn’t returned phone calls, and knocks at his home address in Lawrence have gone unanswered.

Farmer resigned as mayor in August after stepping down as executive director of Just Food. It was discovered he failed to pay more than $50,000 in state and federal payroll taxes for the local nonprofit food bank.

Just Food’s board has alleged Farmer overpaid himself by more than $52,000 over a two-year period. It’s unsure whether he will face criminal charges.
