Madison police identified 27-year-old Karlis Griffin Jan. 9 as the fourth and final suspect involved in the Aug. 1 attack on Badgers running back Montee Ball.
Police originally suspected five men of attacking Ball on the 500 block of University Avenue as he was walking home from State Street Brats around 2 a.m., but police then narrowed the list to four suspects by using video surveillance footage, according to Madison Police Department spokesperson Joel DeSpain.
Ball suffered a concussion as a result of the attack and missed the first week of 2012-’13 preseason football practice.
University of Wisconsin-Madison students Deonte Wilson and Wendell Venerable, 21, and Robert Wilks, 22, are also suspects in the incident.
Wilson pleaded guilty Jan. 18 to disorderly conduct and obstructing an officer, according to Wisconsin Court Records. Additionally, Wilks and Venerable pleaded guilty in December to substantial battery and intended bodily harm for the attack.
