Was there one unisex bathroom. Maybe the victim didn’t realize there was someone in there and was trying to open the door. That doesn’t mean he was attacking the girl.
The defendant was probably charged with 2nd degree murder and offered a plea bargain. If he was convicted of murder, he could probably get life. A jury might convict of manslaughter any way. 90% of cases end in guilty pleas and 95% of civil cases are settled. With the current plea bargain system, the using your right to a jury trial is usually not a good idea.
Plus, a jury might not believe that the victim was really trying to attack the girl.
