A 29-year-old construction worker was killed Tuesday morning when a concrete wall collapsed at a home under renovation in Coconut Grove. 

After nearly seven hours at the scene, the Miami-Dade Medical Examiner's Office removed the body of the victim, identified as Jorge Esteban Rojas, a Cuban man who would have turned 30 next week. His death has prompted a joint investigation involving Miami police and the federal Occupational Safety and Health Administration (OSHA).

The collapse was reported shortly before 11 a.m. at a house in the 2900 block of Southwest 22nd Avenue. According to Miami Police spokesperson Mike Vega, workers had been attempting to knock down one of the home's interior walls when it suddenly gave way.

"We know they were knocking down one of the walls when this 30-year-old worker didn't get out on time, and the wall collapsed on top of him," Vega said.

Across the street, longtime resident Joe Oloza said he heard a loud crash followed by a disturbing yell.

"I heard a loud thump and a very strange yell," he said. "Then the police told me the wall fell on this poor fellow and crushed him."

Loved ones arrived at the scene before 1 p.m., declining to speak publicly but visibly distraught as investigators and construction workers remained behind police tape. 

Miami police say they are investigating whether the proper permits had been obtained for the job. Police say part of their inquiry will focus on who employed Rojas and whether the work was being performed by a licensed contractor.

"This seems like a tragic accident," Vega said. "Of course, we still have to do our investigation… to see about permits and who this person was working for."

A logo for J & M Primos Construction Shell Division was visible at the site. Oloza, who has lived in the neighborhood for more than 30 years, said he noticed remodeling work beginning about a week earlier.

"I think they should have had that thing more braced up," he said. "That house has got to be at least 50 years old."

CBS News Miami reached out to J & M Primos Construction. When asked whether Rojas worked for the company, an employee declined to comment, saying, "I cannot talk about anything."

Police say the investigation is ongoing.
