In Miami, meantime, homicide investigators discovered a body in the trunk of a car that belongs to Gonzalez.

The blue BMW was found at SW 62nd Court and SW 4th Street. Police said the car has been parked in the neighborhood since last Tuesday, the day Gonzalez disappeared.

“We finally opened the car and opened the trunk. We did find a body in the trunk. We can’t confirm whether it is the missing female,” said police spokeswoman Frederica Burden.

“What happened, tell me what happened. I am smelling her,” said Tanya’s father, Ramon Gonzalez demanded of the police. “The foul smell, that’s what I smelled.”

Surveillance pictures from the building where Gonzalez lives shows her in the hallway just before 2 p.m. on September 9th. According to family members, Gonzalez just moved into a new apartment after breaking up with Roy Blanco, her live-in boyfriend of five years.

She was seen at the Shops of Midtown Miami. After that, she was gone.

Gonzalez said Blanco was controlling and obsessive, distancing Tanya from her family, monitoring her phone and stopping Tanya from going anywhere without him.

Gonzalez’s co-workers from the Mojito Bar at Bayside in Downtown Miami were the first ones concerned about her well-being when she didn’t show up for work.

“The way she is we knew something was wrong and I know every second that goes can save her life. It’s too long and its a nightmare. It’s a nightmare. If it’s somebody in the world who doesn’t deserve this its Tanya. Tanya Gonzalez is an angel,” said bar manager Jonathan Tovar.

“She was a special friend, my co-worker. She is awesome. I wish there could be more Tanyas out there. She was happy all the time,” said Lelly Reyes.

Police found Gonzalez’s missing BMW after a neighbor spotted it parked on a side street and called it in. The car was found just blocks away from where Blanco was living.

“Thank you for all your support. Thank you because of your support we are here today and because of your support we will keep moving forward and everything will come to a conclusion,” Gonzalez told those who arrived at the scene after hearing the news.

On Tuesday, police named Blanco a ‘person of interest” in the case. According to Gonzalez’s friends, Blanco was very controlling and jealous when Tanya began to date someone else.

“He was saying ‘I’m gonna kill myself if you leave me’,” said Brahms Alexis. “He was getting rough with her. She was afraid.”

A source close to the investigation told CBS4 News, Blanco hired a private investigator to follow Tanya and purchased a tracking device.

Coast Guard documents obtained by CBS4 show Blanco rented a boat from a Coconut Grove marina the day after Gonzalez went missing. He left with his mother and a dog. He was found the next day off the coast of Key West, stranded after he ran out of gas.

He was rescued by a Good Samaritan and hadn’t been seen until Tuesday in Big Coppitt Key.

The documents show the GPS on the boat had been wiped clean of location information.
