The Harris County Sheriff's Office says it is focused on a section of the creek where sonar equipment detected what could be a body.
Divers with the sheriff's office put on cold water dive suits to search for missing Melissa Sowders, 26. They are hoping to find the pregnant mother of four in Cypress Creek. She is believed to be the victim of foul play.
Texas EquuSearch volunteers have been assisting in the investigation, and EquuSearch is confident this is where her body will be found.
Melissa Sowders was last seen the day after Christmas at a McDonald's not far from the search area. She was there to meet her estranged husband, Matthew, who has since hired a lawyer. We have confirmed that his car is being processed by crime scene investigators.
Detectives say Matthew Sowders is not in custody. Investigators say while he was initially cooperative, he is no longer talking to them.
