An 18-year-old Kennewick man is being held without bail in the Benton County jail for allegedly sexually assaulting a young boy and girl.

Brian Lloyd Haisch appeared in Benton County District Court on Thursday, where a judge found cause to hold him for 72 hours for investigation of first-degree child molestation and attempted first-degree child molestation.

Haisch was arrested by Kennewick police, who began investigating the alleged sex abuse in June. The incidents allegedly happened in August and September 2007.

One victim reported to investigators at Kids Haven that Haisch exposed himself and asked him to touch his penis, court documents said. The boy said he told Haisch, "no."

The second victim said Haisch also exposed himself to her.

Haisch reportedly told investigators that he exposed himself to the girl and got excited by the contact, documents said.
