A 30-year-old woman from Houston, Texas, has been arrested and charged with capital murder after she confessed to murdering her two children, a 7-year-old son and a 5-year-old daughter, on Sunday.

Upon investigation of the police, it was found that the two children, whose names have not been released, were dead under a neighbor's house. Their mother, Sheborah Thomas, admitted to drowning the children in a bathtub last Friday.

What was particularly chilling was the way the crime was brought to the attention of local authorities. Thomas was seen moving out of her house by a man from the neighborhood, who spotted the mother throwing trash in a field. She then asked the man if he could help her move her things from her house.

As the man was helping her with her things, Thomas said something so unbelievable, the man who was helping her initially thought that was telling a very bad joke. She told the man that she had drowned her children.

Local Police spokesperson Kese Smith described how the mother nonchalantly confessed her crime to the man.

"She was so matter-of-fact about it, he didn't think she was serious. He thought she was joking. He continued to help her pack," Smith said.

After a while, however, the man who was helping Smith began to feel something very wrong. As they were driving away from Thomas' house, the man decided to head to the closest police barracks, flagging down an officer and reporting what the woman had said.

When the officers investigated, they were quite shocked to find that the woman was completely right when she admitted that her two children were dead. The man who reported Smith further stated to the police officers that she attempted to bury her children. When this proved too difficult, though, Thomas simply opted to hide her children's bodies under her neighbor's house.

Police have stated that Thomas does not have any previous records of mental issues.
