MIAMI – The ex-boyfriend of a missing Miami woman whose body was believed to be found in the trunk of her car killed himself Tuesday after being found in the Florida Keys.

"It is like my soul is gone," Ramon Gonzalez, whose daughter, Tanya Gonzalez, had been missing since Sept. 9, said Tuesday outside the Miami Police Department.

Earlier in the day, her car was found abandoned near Southwest 62nd Court and Southwest Fourth Street in Miami. Inside, police found a body in the trunk.

Neighbors told Local 10 News the car had been parked there for about a week.

"I want to thank everybody who tried to find my baby," Gonzalez said, weeping as his family tried to comfort him.

Police said they couldn't determine whether the body in the trunk was of a male or female because it was badly decomposed, but items on and around the body indicated it is that of Gonzalez.

Roy Blanco was considered a person of interest in the disappearance of Gonzalez, who was last seen shopping in Miami's Midtown.

Monroe County Sheriff's Office spokeswoman Becky Herrin said deputies found Blanco, 33, with a woman believed to be his mother in Big Coppitt Key.

Herrin said Blanco stabbed himself in the abdomen, while the woman ingested an unknown amount of pills. Blanco was about to be flown to a Miami hospital when he lost consciousness and stopped breathing. Instead, he was taken to Lower Keys Medical Center, where he was pronounced dead.

The woman was also taken to Lower Keys Medical Center.

Gonzalez said Blanco paid the ultimate price.

"He had to kill himself," Gonzalez said.

Authorities said Blanco had chartered a boat from Dinner Key when it ran out of gas near Big Coppitt Key. They said he gave the boat company false contact information and wiped the GPS clean on the trip south.

Blanco was spotted walking along the side of a highway with his mother and dog when someone called 911.

A medical examiner was given the body found in Gonzalez's car to confirm the identity.

Gonzalez's family is planning her funeral for later in the week.
