Pablo Manuel Ibar Casas was born on April 1, 1972, in Fort Lauderdale, Florida. His father, Cándido Ibar, emigrated from Spain to the United States and built a career as a pelotari, a player of a traditional Basque ball sport. Cándido married Cristina Casas, who was of Cuban origin, in 1971. They had two children: Pablo and his younger brother, Michael, born in 1976. Pablo is also related to the famous boxer José Manuel Ibar, known as "Urtain".

Growing up, Pablo began to train to become a professional pelotari, and his debut seemed close. However, an accident occurred. During practice, a ball struck him violently in the right eyebrow, resulting in fifteen stitches. Following the injury, he was advised to take a break from training.

The family moved to Connecticut while Pablo was a teenager. During this time, his mother, Cristina, was diagnosed with cancer. Cándido encouraged Pablo to move to Florida to be closer to her. While in Florida, Pablo started spending time with friends who had a negative influence on him, though he also met a girl named Tanya Quiñones. He fell in love with Tanya, and they eventually got married while he was in prison.

On June 26, 1994, three people were killed in a home in Miramar, Florida. The victims were Casimir Sucharski, the owner of a nightclub called "Casey's Nickelodeon," and two dancers named Sharon Anderson and Marie Rogers. Their bodies were found the next day. They had been beaten and shot. A video camera inside the home recorded the events. Two intruders entered the house, one wearing a hat and sunglasses, and the other covering their face with a T-shirt. The tape showed them attacking the victims for about 22 minutes before stealing money and other items.

Three weeks later, police found Pablo Ibar when he was arrested for another incident. Detectives thought he resembled one of the suspects seen on the surveillance tape. They interrogated him and showed him the video. After this, he was linked to the crime scene. Ibar's friend Seth Peñalver was also suspected of being involved but later found not guilty.

Pablo Ibar's first trial began in May 1997. It ended in a mistrial in January 1998 because the jury could not reach a unanimous decision. There was a lack of solid evidence against him, and he remained in custody. His second trial started in January 1999. During jury selection, Ibar's public defender was arrested, but Ibar's requests for a new lawyer were denied. By June 2000, he was found guilty and sentenced to death, again based on the weak evidence against him.

In 2016, the Florida Supreme Court overturned his death sentence. They said he did not receive effective legal defense and found the evidence insufficient. This led to a retrial. Ibar’s third trial began in November 2018, revealing issues like bribery and witness manipulation. The same witness from the previous trials, Gary Foy, gave inconsistent statements that called his credibility into question. Despite the problems with the case, the jury found Ibar guilty again on May 22, 2019, and sentenced him to life in prison.

Since then, Pablo Ibar has been working with his lawyers to appeal his conviction. His case has drawn attention from the public and various organizations, which continue to support his fight for justice. He is currently serving his life sentence in the Okeechobee Correctional Institution.
