The shooting of a Hialeah man happened after undercover Miami-Dade police officers staged a fake cocaine rip-off aimed at arresting a crew of armed robbers, newly obtained court documents show.

A detective shot and killed Sergio Javier Azcuy, 46, a passenger in a green Kia Sephia stopped by police in West Kendall on May 17.

According to federal and state court documents, investigators say Azcuy and suspected ringleader Heriberto Ortiz thought they were headed to rob a cocaine stash house. Instead, Miami-Dade police pulled the pair over at a staged accident scene to slow traffic and make the arrest.

Azcuy reached for a “dark shiny” object, spurring a Miami-Dade robbery detective to fire twice. Records do not indicate whether Azcuy was armed.

Homicide detectives did find a cell phone in his hand, according to a search warrant.

The documents reveal the first in-depth details of the events that led up to Azcuy’s death.

The undercover operation, conducted in conjunction with federal agents, comes a year after the same Miami-Dade robbery unit arranged a heist that ended when officers shot and killed four armed robbers, including the confidential informant they were working with, in the Redlands.

Because of the ongoing investigation, Miami-Dade police declined to comment on the shooting.

Ortiz, 44, was charged in federal court with conspiracy to distribute cocaine, selling narcotics and interfering with commerce by threat. He is awaiting trial.

Details of the case are laid out in a federal criminal complaint against Ortiz and in a warrant, filed in Miami-Dade Circuit Court, to search the Kia.

This is what happened, according to the documents:

In May 2011, Miami-Dade detective Wayne A. Peart, detached to a federal task force, “received information” that Ortiz was looking for a drug stash house to rob.

Detectives dispatched a confidential informant with the federal Bureau of Alcohol, Tobacco, Firearms and Explosives. Wearing a wire and as undercover detectives videotaped the meeting, the informant met with Ortiz in the parking lot of a Hialeah Sports Authority. He claimed he was a courier and knew of a house used to stash large amounts of cocaine. Ortiz said his Orlando-based crew, which included his brother, would be willing to help with the heist.

The informant insisted on meeting Ortiz’s brother. When Ortiz relayed that to his brother, the brother grew wary, telling Ortiz “that when the police work undercover, they ask to meet all the participants in the robbery.”

The informant assured Ortiz that he only wanted to meet the crew to ensure he got his share of the cocaine. A meeting was set up in Fort Pierce, but later called off because “security and logistical” concerns, according to the complaint.

The proposed heist fizzled. Almost a year later, the informant and Ortiz were talking again.

In April, they were discussing setting up another home invasion robbery, this time with a new crew based in South Florida.

ATF worked the case with Miami-Dade’s Street Terror Offender Program, known as STOP, according to the search warrant.

On April 27, the informant and Ortiz met in the parking lot of La Carreta restaurant in Hialeah. Again, detectives secretly videotaped.

The informant spun a tale: he was to pick up five kilos of cocaine from a stash house. The drugs would be arriving in two weeks, and would be guarded by two armed men.
