Stringfellow was arrested for assault in February 2014. Stringfellow and then teammate Cyler Miles attacked Seattle Seahawks fans following the Super Bowl XLVIII victory over the Denver Broncos. After getting into a fight with a male University of Washington student, Stringfellow then began to intimidate and have an altercation with a female student who had been taking pictures of the incident. "During the struggle, “'Stringfellow hit (her) in the head. (She) fainted, though it appears she was not out for a long period of time (it is unclear whether she passed out from the blow or due to the exertion and the fact she was ill).'” Later in the night, Stringfellow and Miles again approached another man, asked if he was a Seahawks fan and when he replied yes proceeded to assault the fan. When the fan tried to run away, Stringfellow and Miles chased him down and continued to beat him.
