Johnson County Sheriff Adam King is not the father of a child prosecutors claimed was born out of an affair he had in the 1990s, according to DNA test results.

King took a DNA test in May after prosecutors introduced the allegation in court filings, causing his trial to be delayed.

In a statement to WFAA at the time, King’s defense attorney Bill Mason denied the accusations in the court filings, calling them “baseless and laughable.”

Mason said, “Sadly, the State is desperate and has reached a new low. These allegations are false, and the State knows they are false. The Sheriff denies these allegations.”

Jurors at King’s trial, which ended in a hung jury earlier this week, did not hear evidence relating to the paternity claims.

“Based upon the comparison of the DNA of [the mother] to the DNA profile of [her son], the genetic contribution from the biological father of [the son] could be determined,” the DNA test report from the Southwest Institute of Forensic Sciences at Dallas reads. “Adam King is excluded as being the biological father of [the son].”
