LAKE ST. LOUIS, Mo. – Multiple police departments and U.S. Marshals are searching for a serial burglar who they said broke into apartments through sliding glass doors. 

“This is such an invasive crime. He was going into their homes while they were sleeping,” said Captain Joshua Gilliam, Lake St. Louis Police Department.

Gilliam said the investigation includes nine police departments and at least 22 burglaries in just 30 days.

 “When they would wake up, they would find their purses or wallets or valuables that were in plain view were missing,” Gilliam said.

Court records showed Armon Simpson is facing more than 30 charges for six burglaries in Lake St. Louis alone. 

One of those burglaries was caught on camera. 

Police said surveillance cameras showed Simpson using the victims’ credit cards at a gas station in Illinois. 

“He was taking them back to a business in Illinois where he was immediately using those fraudulent credit devices. Which is a lot of what has helped our investigation get to where it is at today,” Gilliam said.

He said Thursday morning U.S. Marshals and detectives from multiple departments found stolen items from several victims inside Simpson’s home. 

“We have a lot of evidence in this case. It is very important for these victims that we hold the suspect accountable for these actions,” Gilliam said.

Police are still searching for Simpson and possible other victims as well.
