A search warrant was served by federal agents at a doctor’s office in McDonald, a spokeswoman for the U.S. attorney’s office confirmed Thursday.

The spokewoman said that agents executed a search warrant at 127 E. Lincoln Ave. on Feb. 28 as part of an ongoing investigation, but declined further comment. That address is the office of Dr. Douglas Dunham.

Several McDonald residents who did not want their names used also said they saw armed officers wearing FBI vests outside the office on that date along with four or five unmarked vehicles. FBI Pittsburgh media coordinator Kelly Kochamba would not comment on the case other than to say that investigators were in the area on that date.

Dunham did not respond to several attempts to reach him for comment.
