Three men — including the owner of a south Florida trucking company — were bound, beaten, shot and left for dead in the backyard of an abandoned home, police said.

Miami-Dade police are investigating a triple shooting on Saturday in Opa-locka that left two men dead and a third in critical condition. Detectives want tips from the public to solve the double homicide — and are offering a $5,000 reward for information leading to an arrest in the grisly slayings.

Two of the men, identified as truckers Osmar Oliva, 50, and Johan Gonzalez Quesada, 26, were found at the abandoned home, while a third victim who has not been publicly identified was airlifted to a hospital in critical condition.

No update on his condition was immediately available early Tuesday, Miami-Dade police Detective Khristopher Welch said.

Several law enforcement sources told the Miami Herald that masked assailants kidnapped the trio and tortured them for hours prior to the shootings. Each victim was shot in the head, including the man who survived and managed to get help from a passerby who called cops, the newspaper reported.

Oliva, a father of three, owned Oliva Delivery Corp., which is based in Opa-locka.

“He was a very good person,” his widow told Herald on Monday. “I don’t know why this happened to him.”

Gonzalez Quesada was also a father of two young girls, including an infant born just 10 days before he was killed execution-style, the Herald reported.

“He was a marvelous person,” the young man’s father, Ovidio Gonzalez Roche, told the newspaper. “He had a huge heart. Very family-oriented … This is such an extraordinary shock. I can’t explain what’s happened.”

No arrests had been made as of early Tuesday. Detectives are looking for three “unknown” male suspects in the triple shooting, police said.

“The investigation is still in its infantile stage,” Welch told The Post, adding that witnesses still need to be interviewed by investigators.

It’s unclear if the victims’ families were cooperating with detectives, Welch said.

Both Oliva and Gonzales Quesada were previously arrested in incidents involving cargo theft, the Herald reported.

In 2007, Oliva was busted when police said he was one of three men spotted unloading cargo from a stolen tractor-trailer, but prosecutors later dropped the charge.

Gonzales Quesada, meanwhile, was arrested last year after two loads of stolen cargo, including frozen shrimp and air conditioners, were found at his home. He pleaded not guilty in the case and was awaiting trial, the Herald reported.

Anyone with information about the slayings should call Miami-Dade County Crime Stoppers at (305) 471-2400.
