From superintendent in the link Goskers provided:
The misconduct allegations included behaviors that do not reflect the professional conduct we expect from coaches in KPS. The behaviors include the following: “fishing” for compliments from various players, saying things like “I’m fat and I don’t know why my wife is married to me” only to have players refute those comments, driving a team van to a summer tournament where the song “Wet A** P****” by Cardi B was played and potentially sang by all in the van including Coach Carson who “didn’t remember”, handing out awards at a team banquet that included an award to “the girl who got the most SnapChat numbers from guys on road trips”, and taking a selfie with the players who were clad in bikinis on a summer trip. To be very clear, the most serious allegation of misconduct included a flirtatious relationship and preferential treatment of a specific player... There has never been, nor was there any evidence to suggest that any inappropriate physical relationship occurred between Coach Carson and a player.
