The Florida Dept. of Agriculture filed paperwork for a $150,000 fine from G4S this week.

The state said G4S believes it gave the mental health screenings, but listed the wrong psychiatrist on the paperwork.

After the Pulse attack, investigators looked at Mateen's nine-year record as a security guard for the company, first with the St. Lucie County Courthouse and then for a neighborhood.

The state says guards were supposed to be given mental health screenings, but the psychiatrist the company listed left her practice in 2006.

Mateen joined G4S in 2007.

The state says that psychiatrist is listed on at least 1,500 applications after 2006. They say this happened for almost a decade.

Mateen killed 49 people and injured dozens more at the Pulse nightclub in June. He was killed by police.
