Prosecutors say he had been talking to the boss's 11-year-old daughter through instant messages for 30 minutes last week. They contained explicit sexual questions.
Harris County Assistant District Attorney Eric Devlin said, "The chats talk about extreme desire and extreme interest and all the things he wanted to do to her."
And Devlin says Rohrman knew whom he was asking.
"He knows her in person and knows full well how old she is," Devlin explained.
The victim's mother reportedly found inappropriate sexual references in the messages between the Rohrman and the girl in a 30 minute conversation on Facebook.
Rohrman was arrested on Thursday by Lakeview police. He's charged with online solicitation of a minor. His bail has been set at $50,000.
Investigators aren't sure whether Rohrman, who lives in Webster, has targeted other girls. He's a married father of two boys, now charged with a felony and who may or may not be unemployed. If you have any information about other possible victims, you're asked to call the Lakeview Police Department at 281-326-5900.
