"Orlando, Florida (CNN) -- A 40-year-old man accused of killing one and wounding five in a shooting at a business where he once worked was charged Friday with first-degree murder, police said.

"I'm just going through a tough time right now, I'm sorry," the 40-year-old suspect who had recently declared bankruptcy allegedly told police as he was taken into custody.

Authorities identified the suspect as Jason Rodriguez, a former employee of Reynolds Smith & Hills, whose offices are located in the 16-story Gateway Center building.

The incident began at 11:44 a.m., when Rodriguez entered the business' eighth-floor reception area, said Lt. Louis Tanzi, violent crimes section commander for the Orlando Police Department.

"He produced a handgun and started shooting in the reception area and continued shooting in the entire office area until he left," he told reporters.

According to the charging affidavit, the fatality occurred when Rodriguez entered the suite, pulled a handgun from a holster under his shirt and shot twice at an employee who was standing near the receptionist's desk.

He then entered a common work area "firing multiple rounds and causing injuries to several other employees," it says, citing a witness.

During the incident, Rodriguez "was recognized by numerous former co-workers," it says.

He then left in a car, described by witnesses as a small, silver compact vehicle, the affidavit says.

Police went to his residence where they found a 2001 four-door silver Hyundai, it says.

Asked by a reporter why he allegedly committed the crime, Rodriguez, escorted by police, said, "They left me to rot."

Paraded in front of reporters outside the police station, he said, "Innocent.""
