Dash cam video from a police pursuit that led to a crash on Monday has been released.

Video from a Gulfport police cruiser shows the almost 15 minute pursuit of 21-year-old Derrick Mims.

Officer Jessie Kellington ran the license plate of the car Mims was in and discovered it was stolen.

When he turned on his sirens, his dash cam began to record Mims' every move. The chase began on Newton Avenue South and 51st Street in Gulfport.

Mims led police through about 30 turns as raced through parts of Pinellas County.

Gulfport Police Chief Robert Vincent said he stands behind the high-speed chase.

"We own it, it was absolutely something that was initiated by Gulfport, but the fact is what happened yesterday was because of the actions of Derrik Mims, not because of the actions of the Gulfport Police Department," said Vincent.

The Chief said the chase reached speeds around 90 miles-per-hour on I-275 and about 40 miles-per-hour through the Jordan Park neighborhood.

The chase ended about 15 minutes after it began, when the car crashed into a bus. The bus then slammed into an apartment building.

Only then, according to Chief Vincent, did the officer discover a 2-year-old child in the backseat. The toddler was not buckled in.

"I know Officer Kellington pretty well and I think that if he knew there was a child in the car he probably would have decided not to pursue," said Chief Vincent.

The Chief said he has no intention of changing any part of the current policy but will review the entire incident per protocol. He said they will complete a checklist and compare it to the evidence in the case to determine if there were any parts of the policy that were not followed.

Chief Vincent said the pursuit policy was expanded about two years ago because of an increase in stolen vehicles.

Mims is in the Pinellas County jail. The little boy is now with his mother.
