Wray, who is on vacation, and Kosovac did not return calls Thursday.

According to the Madison comptroller's office, Markham has also used vacation and sick time for a portion of the period she has been off work.

City records show Markham earned $89,160 last year, including salary, overtime and other compensation. Her current annual salary is $65,988.

Markham declined to comment on the investigation Thursday. She continues to serve as a constable for the town of Rutland, a position she has held for several years.

Andrew Schauer, an attorney with the Wisconsin Professional Police Association who is representing Markham, said, "It would be improper for us to comment while the investigation is ongoing."

Schauer would not discuss the scope of the investigation, but said the length of the investigation shows the Police Department is looking into the matter thoroughly.

"We believe the public will have full confidence in Officer Markham's ability to return to the force," Schauer said.

Officer Dan Frei, president of the Madison Professional Police Officers Association, said he would not comment on any investigation involving an officer.
