A Colorado man was freed by emergency rescue crews from a department store wall Tuesday after being trapped there for at least two days. Police and firefighters had to slice into the walls in order to remove the stuck man.

According to the Longmont Times-Call, Paul Felyk got trapped in a vacant space between an interior and exterior wall at a Marshalls store. Police said the 35-year-old man entered the infrastructure through the roof before he fell about 20 feet.

Employees of the Marshalls store told police that they could hear a man yelling Monday morning, but couldn't figure out where the noise was coming from.

On Tuesday, it was discovered that the man was yelling for help through a small hole in the store's back wall. It was not immediately clear when Felyk fell into the wall or how long he was trapped.

Felyk was able to push notes through the hole in an attempt to describe where he was within the interior walls of the store. One of the notes sent through the wall was dated Nov. 8, leading investigators to believe that Felyk had been trapped since Saturday, but that information could not be immediately confirmed.

Firefighters reportedly spent nearly 30 minutes Tuesday morning freeing Felyk from the space. Once a hole was opened in the outside wall, Felyk crawled out and was immediately taken to a local hospital.

A police spokesman later said Felyk was still in the hospital that afternoon due to injuries to his lower extremities.

The Times-Call reported that Felyk has prior convictions for robbery, trespassing, driving while ability impaired, theft, assault and criminal mischief. It is thought that he may be a transient.

Police are investigating further into the incident, as it could have been a possible burglary or trespassing and charges are reportedly pending.

Felyk's presence in the building's walls might have been related to other nearby businesses having difficulties with phone lines, Internet services and heating systems, which authorities are also looking into.
