Two children's remains found. Plus mother?

The bodies of two children were found in a canal Wednesday, March 2nd. In Delray Beach, Fl. The police were called to the canal about a floating duffel bag. In that duffel bag, police found the body of a young girl. After farther investigation, they believe she is around six to ten years of age. During the search, divers stumbled upon a suitcase. This suitcase held the body of a young boy. Investigators believe he is around the age of ten or twelve. Both children are African American and are believe to be siblings. The girl had braided hair with beads on the end. Wearing dark pants and a short-sleeved shirt. The boy was only wearing dark blue shorts. The police stated that they believe this is a domestic issue. The canal that they were found in is the dividing line between Delray Beach and Boca Raton. This canal stretches for miles both directions. This meaning they could have been dumped anywhere among the banks. The remains of the two children were taken to Palm Beach Medical Examiner's office to find out the cause of death. Experts also believe that the bodys were dumped into the water recently because they were still intact. As of thursday they were still investigating the canal. Although, the current could have carried evidence far away from where the bodies were found.
About seven months prior to the findings of these children's remains, a woman was found in a landfill. Police believe that this woman could be the childrens mother. The name of the woman is Felicia Brown. She was never reported missing. Authorities only began looking for her because she was thought to be the mother of the children found wednesday. The medical examiner is using dental records to determine whether the children are siblings and are infact, Mrs. Brown's children. Margaret Gissome, Felicia's sister, told police that Felicia kind of "dissappeared" after their mother's funeral in 2007.
"I never knew my sister was missing. I never knew my niece or nephew were missing." Says Gissome, "There are a lot of questions going on."
The investigation continued and became more interesting when authorities announced they had arrested their only suspect. A man that goes by, Clem Beauchamp. Which just happens to be Felicia Brown's ex-boyfriend. The same day that the children's bodies were found, Beauchamp went to authorities and volunteered to talk to investigators. Although, he has yet to be charged with anything.
Three other children that lived in the home with Beauchamp and Brown are now safe in custody.

This newsline really got my attention. Mainly. because it is really sad to see any children go through this. Also, to see how the investigation intensified by the findings of the mother. Hopefully they will indeed, charge Beauchamp and have another criminal off the streets! That is, if in fact he is responsible.
