A La Crosse police investigator showed the court text messages alleged to be between a 28-year-old man and an underage girl he is accused of sexually assaulting. Steven Meyer has entered not guilty pleas to charges of having sex with a child age 16 or older and child enticement. The girl told police Meyer gave her alcohol and marijuana before having sex with her while she was drunk. Meyer made his first La Crosse County court appearance this week. He is scheduled to return to court in June.
