On August 31, San Jose police responded to reports of domestic violence about 2:45 a.m. in the 2500 block of Bentley Ridge Drive where McDonald lives, police said. McDonald was arrested on suspicion of domestic violence against his pregnant fiancée.

Weeks later, the Santa Clara County District Attorney’s office said it would not prosecute because both McDonald and his fiancée stated she struck him first and her injuries were consistent with being restrained.

“The People will not be able to convince twelve jurors unanimously and with proof beyond a reasonable doubt that McDonald did not act in self-defense,” read a memo from Supervising District Attorney Cindy Seeley Hendrickson to District Attorney Jeff Rosen. “Therefore, we cannot prove a crime occurred.”

“I knew what kind of guy I was and what kind of upbringing I had and that I respect women. I knew the truth would come out like I said that it would eventually come out,” McDonald said at the time.
