MANKATO — The son of Hennepin County Sheriff Rich Stanek has been charged with trying to solicit a 13-year-old for sex and possessing child pornography.

Ryan James Stanek, 24, of Maple Grove, was charged with four felony counts Wednesday in Blue Earth County. He’s due in court June 22.

According to the criminal complaint, some of the pornographic images found on the cellphone he used involved children as young as 3.

The investigation started in late March when the father of a young adult woman reported to the Sibley County sheriff’s office that Ryan Stanek was sending her sexual text messages. The sheriff’s office called in the state Bureau of Criminal Apprehension. The complaint alleges the defendant asked the woman to find girls for him to have sex with, and expressed interest in her 13-year-old cousin.
