The victim read a letter to her assailant regarding the impact this has had on her during the proceedings.
Via BuzzFeed:
One night in January 2015, two Stanford University graduate students biking across campus spotted a freshman thrusting his body on top of an unconscious, half-naked woman behind a dumpster. This March, a California jury found the former student, 20-year-old Brock Allen Turner, guilty of three counts of sexual assault. Turner faced a maximum of fourteen years in state prison. On Thursday, he was sentenced to six months in county jail and probation. The judge said he feared a longer sentence would have a “severe impact” on Turner, a champion swimmer who once aspired to swim in the Olympics — a detail repeatedly brought up during the trial.
On Thursday, Turner’s victim addressed him directly, detailing the severe impact his actions had on her — from the night she learned she had been assaulted by a stranger while unconscious, to the grueling trial during which Turner’s attorneys argued that she had eagerly consented.
The full letter the Stanford victim read to hear assailant describing the impact on her is posted at BuzzFeed. I was going to excerpt a quote, but the letter is so powerful and important, I just want to encourage you to read it in its entirety instead.

Disgusting. Evidence that some still treat rape like it is some unfortunate thing that just happens between 2 people, instead of something that 1 person does to another.
I think the letter from the victim is incredible and should be read by everyone who has not been sexually assaulted. Content note for some very upsetting material related to sexual assault.

And then, here’s the letter Brock Turner’s father wrote to the judge, asking that his son not be punished too harshly for a 20-minute mistake.
