SHERMAN, TX - Grayson County Criminal District Attorney John Kermit Hill has announced a landmark sentence for a Pottsboro man convicted of horrific crimes against a child. On Wednesday, January 14, 2026, Kristofher Dahn, 40, was sentenced to three 99-year prison terms by the 15th District Court.
Following a jury trial, Dahn was found guilty of one count of Continuous Sexual Abuse of a Child Under 14 and two counts of Aggravated Sexual Assault of a Child.
Investigation and Flight
The case began on July 17, 2024, when the young victim made an outcry to her mother. A specialized investigation followed, involving:
-
Forensic Interviews: Conducted by the Grayson County Child Advocacy Center, which determined the abuse had been ongoing since early 2023.
-
Medical Evidence: The victim underwent a Sexual Assault Nurse Examiner (S.A.N.E.) exam to document the abuse.
-
Apprehension: After a warrant was issued, Dahn fled Texas for Louisiana—leaving behind his biological daughter. He eventually turned himself in several days later and was extradited back to Grayson County.
The Verdict and Sentencing
Presided over by Judge Jim Fallon, the trial concluded with the jury assessing the maximum possible punishment for the continuous abuse charge.
District Attorney John Kermit Hill emphasized that the 99-year sentence for Continuous Sexual Abuse effectively ensures Dahn will never be a free man again. Under Texas law, this specific charge requires the defendant to serve nearly the entirety of the sentence.
“This defendant and those like him are a menace to society... the sentence in this case is very appropriate in light of the fact that he gave this child a life sentence of unimaginably cruel and disgusting memories,” said District Attorney John Kermit Hill.
Permanent Protections
In addition to the prison time and $20,000 in fines, the court has implemented permanent measures to protect the survivor and the public:
-
Lifetime Protective Order: The victim is legally protected from any future contact with Dahn.
-
Lifetime Sex Offender Registration: Should Dahn ever be released, he would be subject to the strictest registration requirements for the remainder of his life.
The case was prosecuted by Assistant District Attorneys Eli Brown and Suresh Kumar.
