The following is taken from wikipedia and from the other sources i have read is pretty accurate.
The 1986 FBI Miami shootout was a gun battle that occurred on April 11, 1986 in an unincorporated region of Miami-Dade County in south Florida between eight Federal Bureau of Investigation (FBI) agents and two serial bank robbers. During the firefight, Special Agents Jerry L. Dove and Benjamin P. Grogan were killed. The two robbery suspects, William Russell Matix and Michael Lee Platt, were also killed. In addition, five FBI agents were wounded in the incident.

Michael Lee Platt (February 3, 1954 – April 11, 1986) and William Russell Matix (June 25, 1951 – April 11, 1986) met while serving in the Army in the 1970s. Matix first served in the Marine Corps from 1969–1972 and was honorably discharged. In 1973, Matix enlisted in the Army and served in the military police. Matix was honorably discharged from the army in 1976. Platt enlisted in 1972 as an infantryman and served with the U.S. Army Rangers. He was honorably discharged in 1979. The pair met while they were stationed at Fort Campbell in Kentucky. Both men had been previously married to women who had died under mysterious circumstances.Matix's wife, Patricia Buchanich, was stabbed to death along with a co-worker on December 30, 1983 at Riverside Methodist Hospital in Columbus Ohio, where both women worked. Matix was a suspect in her murder but was never charged.After his wife's death Matix moved to Miami at the urging of Michael Platt. After relocating to Miami, Matix began a landscaping business with Platt.In December 1984, Platt's wife Regina was found shot dead with a shotgun. Her death was ruled a suicide.

Prior to embarking on their crime spree neither Platt nor Matix had a criminal record.

On October 5, 1985, Platt and Matix murdered 25-year-old Emelio Briel while he was target shooting at a rock pit. The pair stole Briel's car and used it to commit several robberies. Briel's remains were found on March 1, 1986 but were not positively identified until May 1986.

On October 16, 1985, Platt and Matix attempted to rob a Wells Fargo armored truck in front of a Winn-Dixie supermarket. One of the pair shot a guard in the leg with a shotgun. Two other guards returned fire. Neither Platt nor Matix was injured. No money was taken in the botched robbery.

On November 8, 1985, Platt and Matix robbed a teller station outside a branch of the Florida National Bank. Ninety minutes later, Platt and Matix robbed a branch of the Professional Savings Bank. The pair used Briel's stolen car in the second robbery.

On January 10, 1986, Platt and Matix robbed a Brinks armored truck. One suspect shot the guard with a shotgun while the other shot him with a rifle. The guard survived. Platt and Matix used Briel's stolen car in this incident. The pair were followed from the scene by a citizen who saw them switch to a white Ford F-150 pickup truck.

On March 12, 1986, Platt and Matix robbed and shot Jose Collazo while Collazo was target shooting at a rock pit. The pair left Collazo for dead and stole his car, a black 1979 Chevrolet Monte Carlo. Collazo survived the shooting and walked three miles to get help.

On March 19, 1986, the pair used Collazo's car to rob the Barnett Bank at 13595 South Dixie Highway.

The shootout

At 8:45 a.m on April 11, 1986, a team of FBI agents led by Special Agent Gordon McNeill assembled at a Home Depot to initiate a rolling stakeout searching for the black Monte Carlo (Collazo's stolen car). The agents did not know the identity of the suspects at the time. They were acting on a hunch that the pair would attempt a robbery that morning.

A total of fourteen FBI agents in eleven cars participated in the search. Eight of these FBI agents took part in the actual shootout and were paired as follows;

* Supervisory Special Agent Gordon McNeill alone in his car

* Special Agent Richard Manauzzi alone in his car

* Special Agent Benjamin Grogan, with
* Special Agent Jerry Dove

* Special Agent Edmundo Mireles, Jr., with
* Special Agent John Hanlon

* Special Agent Gilbert Orrantia, with
* Special Agent Ronald Risner

Around 9:30 a.m., agents Grogan and Dove spotted the suspect vehicle, and began to follow. Two other stakeout team cars joined them, and eventually an attempt was made to conduct a felony traffic stop of the suspects, who were forced off the road following collisions with the FBI cars of agents Grogan/Dove, agents Hanlon/Mireles and agent Manauzzi. This sent the suspect car nose first into a tree in a small parking area in front of a house at 12201 Southwest 82nd Avenue, pinned against a parked car on its passenger side and Manauzzi's car on the driver side.

Of the eight agents at the scene, two had shotguns in their vehicles (McNeill and Mireles), three were armed with semi-automatic 9mm pistols (Dove, Grogan, and Risner), and the rest were armed with revolvers.

The initial collision that forced the suspects off the road caused some unforeseen problems for the agents, as the FBI vehicles sustained damage from the heavier, older car driven by Matix.Just prior to ramming the Monte Carlo, Manauzzi had pulled out his service revolver and placed it on the seat in anticipation of a shootout. but the force of the collision flung open his door and sent his weapon flying. Hanlon also lost his .357 Magnum service revolver during the initial collision, though he was still able to fight with his Smith & Wesson Model 36 backup gun. The collision also knocked off Grogan's eye glasses, making it difficult for him to see.

Manauzzi was wounded when Matix fired his shotgun and the pellets penetrated the door of Manauzzi's car. McNeill fired over the hood of Manauzzi's car but was wounded by return fire from Platt's Ruger Mini-14 rifle. Platt then fired his rifle at Mireles across the street. Mireles was hit in the left forearm, creating a severe wound.[7] Platt then pulled back from the window, giving Matix opportunity to fire. Due to collision damage, Matix could only open his door partially, and fired one shotgun round at Grogan and Dove, striking their vehicle. Matix was then shot in the right forearm, probably by Grogan.

McNeill returned fire with six shots from his revolver, hitting Matix with two rounds in the head and neck. Matix was apparently knocked unconscious by the hits and fired no more rounds.McNeill was then shot in the hand, and due to his wound and blood in his revolver's chambers, could not reload.

As Platt climbed out of the passenger side car window, one of Dove's 9 mm rounds hit his right upper arm and went on to penetrate his chest, stopping an inch away from his heart. The autopsy found Platt’s right lung was collapsed and his chest cavity contained 1.3 liters of blood, suggesting damage to the main blood vessels of the right lung. Of his many gunshot wounds, this first was the primary injury responsible for Platt’s eventual death.The car had come to a stop against a parked vehicle, and Platt had to climb across the hood of this vehicle, a Cutlass. As he did so, he was shot a second and third time, in the right thigh and left foot. The shots were believed to have been fired by Dove.

Platt took up position by the passenger side front fender of the Cutlass. He fired a .357 Magnum revolver at agents Ronald Risner and Gilbert Orrantia, and was shot a fourth time when turning to fire at Hanlon, Dove and Grogan. The bullet, fired by Risner or Orrantia, penetrated Platt's right forearm, fractured the radius bone and exited the forearm. This wound caused Platt to drop his revolver.It is estimated that Platt was shot a fifth time shortly afterwards, this time by Risner. The bullet penetrated Platt's right upper arm, exited below the armpit and entered his torso, stopping below his shoulder blade. The wound was not serious.

Platt fired one round from his Mini-14 at Risner and Orrantia's position, wounding Orrantia with shrapnel created by the bullet's passage, and two rounds at McNeill. One round hit McNeill in the neck, causing him to collapse and leaving him paralyzed for several hours. Platt then apparently positioned the Mini-14 against his shoulder using his uninjured left hand.

Dove's 9 mm pistol was rendered inoperative after being hit by one of Platt's bullets. Hanlon fired at Platt and was shot in the hand while reloading. Platt aggressively advanced on Grogan and Dove's car, which they were using as cover. Reaching their position, he continued firing. Platt killed Grogan with a shot to the chest, shot Hanlon in the groin area and then killed Dove with two shots to the head. Platt then entered the Grogan/Dove car in an apparent attempt to flee the scene.
As Platt entered Grogan and Dove's car, Mireles, able to use only one arm, fired the first of five rounds from his pump-action shotgun, wounding Platt in both feet.
At an unknown time, Matix had regained consciousness and he joined Platt in the car, entering via the passenger door. Mireles fired four more rounds at Platt and Matix, but hit neither.

Around this time, Metro-Dade Police Officers Leonard Figueroa and Martin Heckman arrived. Heckman covered McNeill's paralyzed body with his own.

Platt's actions at this moment in the fight have been debated. A civilian witness described Platt leaving the car, walking almost 20 feet and firing at Mireles three times at close range. Mireles does not remember this happening. Officer Heckman does not remember Platt leaving the Grogan/Dove car. Risner and Orrantia, observing from the other side of the street, stated that they did not see Platt leave the car and fire at Mireles.However, it is known for certain that Platt pulled Matix's Dan Wesson revolver at some point and fired three rounds.

Platt attempted to start the Grogan/Dove car. Mireles drew his .357 Magnum revolver, moved parallel to the street and then directly toward Platt and Matix. Mireles fired six rounds at the suspects. The first round missed, hitting the back of the front seat. The second hit the driver's side window post and fragmented, with one small piece hitting Platt in the scalp.

The third hit Matix in the face, and fragmented in two, with neither piece causing a serious wound. The fourth hit Matix in the face next to his right eye socket, travelled downward through the facial bones, into the neck, where it entered the spinal column and severed the spinal cord. The fifth hit Matix in the face, penetrated the jaw bone and neck and came to rest by the spinal column.Mireles reached the driver's side door, extended his revolver through the window, and fired his sixth shot at Platt. The bullet penetrated Platt's chest and bruised the spinal cord, ending the gunfight.

When the medics arrived Platt was still showing some signs of life but died not long after.
Matix was already dead.
Grogan and Dove were dead at the crime scene.

The shootout involved ten people: two suspects and eight FBI agents. Of the ten, only one, Special Agent Manauzzi, did not fire any shots (firearm thrown from car in initial collision), while only one, Special Agent Risner, was able to emerge from the battle without a wound. The incident lasted under five minutes yet approximately 145 shots were exchanged.

Toxicology tests showed that the abilities of Platt and Matix to fight through multiple traumatic gunshot wounds and continue to battle and attempt to escape were not achieved through any chemical means. Both of their bodies were drug-free at the time of their deaths.
