ST. LOUIS — Numerous officers from the FBI and St. Louis Metropolitan Police Department responded to a Dutchtown home with an excavator Thursday morning.

Department spokesperson Mitch McCoy told 5 On Your Side that detectives executed a search warrant at the home on Dewey Avenue near Delor Street around 7:30 a.m. He said the investigation stems from a missing person case from 2020.

Police detained a man and a woman at the home after the search warrant was executed, the identities of which have not been shared. The woman was arrested for outstanding warrants. McCoy said only suspected narcotics had been found at the scene.

FBI agents from the evidence response team began assisting in the scene's investigation after the search warrant was executed. Officials were seen scanning the residence's backyard with unknown equipment. At around 1 p.m., investigators and the excavator began digging up a portion of the home's backyard.

McCoy also wanted to dispel rumors that recently spread on social media, claiming there is a mass grave or the bodies of babies buried in the yard.

This is a developing situation. This article will be updated with the latest information as it is released.
