A Florida mom who was reported missing last week was found on Thursday trapped inside a shipping container, police said. 

Marlene Lopez, 52, was last seen Monday at her home on Lucerne Drive, according to a press release from the Cocoa Police Department. A coworker, concerned about her well-being, called the police after Lopez failed to pick up her son. 

Detectives investigated "known locations," interviewed family members, and issued a missing person bulletin. 

During the investigation, detectives were notified that the woman had been found trapped in a shipping container next to a business at 2005 N. Cocoa Blvd.
