Search warrants were served about 4 p.m. Wednesday at Livingston County's 53

District Court, as well as at Brennan's private residence, MSP spokeswoman Lori Dougovito confirmed.

Property was taken as part of an ongoing criminal investigation, but police did not disclose the nature of the probe, and Dougovito declined to comment on what was taken.

"As with any investigation, regardless of whom the investigation involves, our one and only goal is to be a finder of fact and relay those facts to the Attorney General's office," state police said in a statement.

Brennan, who could not immediately be reached for comment, has come under scrutiny after divorce proceedings exposed an affair she had with state police First Lt. Sean Furlong.

Brennan presided over a 2013 double murder case in which Furlong was lead detective, according to a report by the Livingston Daily.

Brennan and Furlong testified in depositions during divorce proceedings that they spoke once during the trial and that their relationship did not begin until afterward, according to the Livingston Daily.

The man convicted in the murders - Jerome Walter Kowalski - is seeking to have his conviction set aside due to allegations that Brennan committed perjury in those statements about the trial.
