GREEN BAY- Authorities continue to investigate the suspected assault of an 11-month-old baby.

Derek D. Gates of Clinton, Ark., 37, was arrested July 28 on suspicion of sexually assaulting the daughter of his girlfriend. The couple brought the baby to the hospital after the child's mother found blood in her diaper. The woman told authorities the baby had no injuries or bleeding the night before.

During a July 31 probable cause hearing Gates' bail was set at $50,000.

A criminal complaint filed Aug. 22, mentions the baby and her injuries, but also details authorities searching the hotel room where Gates, his girlfriend and her two children were staying. During the search, Gates told police that he had a small amount of marijuana in a drawer.

Gates is now facing one count for possession of marijuana. His bond was reduced to $250 and he is scheduled to appear in court at 10:15 a.m. Oct. 3.

How the child was injured is still under investigation.

According to a statement from Brown County District Attorney’s office, "The case is still under investigation including further work being performed by the crime lab."

No timeline was available for when the lab results were expected back.
