A St. Clair man is behind bars with no bond after police say a late June report of a sexual assault within a family led to a warrant alleging statutory sodomy involving a child under 12. Authorities identified Isaac James Sansoucie as the suspect and arrested him at his St. Clair home on July 3. He is being held at the Franklin County Adult Detention Facility, and the case has been forwarded to the Franklin County prosecuting attorney's office for review.
According to a media release from the St. Clair Police Department, officers first received the report on June 30 and later identified Sansoucie as the suspect. The release states that a warrant was issued for "statutory sodomy or attempted statutory sodomy, deviate sexual intercourse, person less than 12 years of age," and that charging documents were sent to the Franklin County Prosecuting Attorney's Office for review. Investigators also reported that Sansoucie refused to speak with detectives without his attorney present, which is his legal right.
St. Clair officers, working with deputies from the Franklin County Sheriff's Department, arrested Sansoucie at his residence on July 3, the St. Clair Police Department release says. He is being held on no bond at the county facility while prosecutors review the case file. The release also notes, "All persons are considered innocent until proven guilty in a court of law."
Statutory sodomy charge and potential penalties
Missouri law treats alleged "deviate sexual intercourse" with a minor as a top tier felony. Statutory sodomy in the first degree and related offenses, particularly those involving a child under 12, are laid out in the state criminal code and can bring very long prison sentences. The statutes and legal summaries note that penalties can run to decades in prison or, in aggravated situations, life imprisonment. The precise potential sentence in any case depends on what charges prosecutors ultimately file and what a court finds. For the statute text, see the Missouri Revised Statutes.

What comes next
The police release says charging documents have been forwarded to the Franklin County Prosecuting Attorney's Office for review, which is the routine step before any formal filing. If prosecutors decide to move ahead, Sansoucie would be arraigned and the case would move into preliminary court proceedings. Until that happens, he remains presumed innocent under the law.
