Deputy Tommy "Hawk" Hill is played by Michael Horse.
Born in 1951, he works at the Twin Peaks sheriff's department under Sheriff Harry S. Truman.
He is a Native American, but it is not made clear to which tribe he belongs, although during a discussion as to whether or not Tommy believes in the soul he references Blackfoot Indian mysticism to Special Agent Dale Cooper. He is usually referred to as "Hawk" because of his excellent tracking skills, which extend beyond animal and human tracks to those of cars and trucks.
He is clearly aware of the supernatural presence in woods of Twin Peaks and also discusses with Cooper his belief in a direct connection to Native American spirituality. He is also the first person to verbally express to the viewers (as well as to Cooper) what the White Lodge and Black Lodge are.
One of The Bookhouse Boys and an all-around dependable good guy, he saves the lives of both Truman and Cooper on more than one occasion. He has an unseen girlfriend who is a ER Nurse at Calhoun Memorial Hospital in Snoqualmie, Washington.
