Former teacher to face El Dorado County charge

Charles Sizemore

Karsten Gronwold will be sentenced Oct. 29 in Sacramento before U.S. District Judge William B. Shubb, following his guilty plea last month to possessing visual depictions of minors engaged in sexually explicit conduct.

The sentencing, however, will not bring an end to a case that started over a year ago with the arrest of Gronwold, 50, of South Lake Tahoe, on federal charges related to child pornography. At the time, Gronwold taught at the Lake Tahoe Environmental Science Magnet School.

The El Dorado County District Attorney’s Office is charging him with one count of lewd and lascivious conduct with a minor under the age of 14, Deputy District Attorney Lisa Serafini said Wednesday. Once finished with the federal charge, Gronwold will have to travel to South Lake Tahoe to answer to the local charge, Serafini said.

As part of his guilty plea in the federal case, Gronwold admitted that he had possessed hundreds of pictures of minor boys engaged in sexual acts, including a sexually explicit picture of himself and a minor, according to a press release from U.S. Attorney McGregor W. Scott. Gronwold did not take responsibility for the production of the image, but agreed for his sentence to be based upon the production, according to the press release.

Gronwold and the prosecution have agreed to a sentence of 97 months, although the actual length of the sentence is at the discretion of the court.

El Dorado County Sheriff’s Department and the Sacramento Valley Hi-Tech Crimes Task Force teamed up in the investigation of the case as part of a Project Safe Childhood, and was the result of complaints made to the National Center for Missing and Exploited Children’s CyberTipline.
