A Farmington man has been charged with three counts of second-degree murder, accused of shooting his brother and father in the head, then bludgeoning his mother to death inside a home earlier this week.

Blake Thomas Maloney, 26, was arrested at the scene of the triple homicide on the 400 block of 183rd St. W. on Wednesday, Oct. 27, and was booked into the Dakota County Jail, with formal charges filed Friday.

Wednesday at about 9:30 p.m., officers arrived after a caller reported their ex-girlfriend—later identified as Tracy Maloney, 53—had gone to her ex-husband’s home earlier that evening to visit her sons. The caller couldn’t contact Tracy for several hours and wanted police to check the home.
