Keenan was mayor from 2010-2011 and billed himself as a devout Christian. He has now confessed to three years of sexual contact with the child starting when she was only four. He can now face life imprisonment.
The interesting legal element is that the abuse came to light during group discussions at a hospital. He later checked himself into a psychiatric clinic because he was suicidal. The question will now be whether the statements are admissible in court. There is a good chance that they are admissible since this was not a police or government agent eliciting the statements and it was the basis for someone to call the police. It is also hard to maintain privilege in a group settings and there is a crime/fraud exception to privilege claims.
In addition there are accounts of Keenan discussing the issue with a minister and with family members. The minister conversion would be privileged. The assaults occurred in September 2015.
