A death investigation is underway Tuesday in Cutler Bay at the same home where two sex assault suspects were arrested last week.
Miami-Dade police said two people were found inside a car behind the home by a friend who called 911 at about 7 a.m.
Local 10 News reporter Layron Livingston saw a hose at the scene that appeared to be attached to the car.
Police said a man was pronounced dead at the scene and a woman was taken to a hospital. Their identities have not been released.
The investigation is happening along Southwest 185th Terrace and Southwest 87th Avenue at the home of Dale Leary.
"We do have an ongoing investigation at this residence in regards to a sexual crime that occurred," Miami-Dade police Detective Argemis Colome said.
On June 27th, police arrested Leary and his wife, Marta San Jose, for allegedly sexually assaulting her younger teen sister.
Miami-Dade police detectives said San Jose was 16 when she left Spain for South Florida in 2012. Leary, who was a sponsor for students in an international student exchange program, let San Jose stay with him at his home.
After San Jose finished 11th grade, she and Leary flew to Spain to convince her parents to let her stay for another school year, detectives said.
Once San Jose turned 18, Leary divorced his wife and married San Jose, unbeknownst to her parents, police said.
According to the arrest affidavits, San Jose invited her then-14-year-old sister to stay with her and Leary in 2014.
A few days after San Jose's sister arrived in South Florida, she learned that her sister and Leary were married.
Detectives said San Jose manipulated her sister into believing that she was molested by her parents when she was very young and persuaded her sister to allow Leary to conduct a vaginal examination "to prove she was sexually assaulted."
San Jose told her sister that Leary had married her "so she could stay" in the U.S. "and avoid going back home" to her sexually abusive parents, the arrest affidavits said.
A few days later, Leary and San Jose started having sex in front of the girl, police said. The girl said her sister would tell her to allow Leary to perform sex acts on her, convincing her to remove her clothes.
Detectives said Leary performed oral sex on San Jose and her sister, and then made them perform oral sex on him, on more than seven different occasions.
The girl told police that Leary, who was a photographer, wanted to take pictures of her, and he made her consume alcoholic beverages during one of the photo sessions. Once she was intoxicated, Leary made her remove her clothes except for her high heels and pose for him with her naked sister, detectives said.
In some of the poses, Leary had the sisters hug, causing their breasts to touch, detectives said.
Leary and San Jose were arrested on multiple charges, including lewd and lascivious conduct on a child and sexual performance by a child.
Police said San Jose's sister was reunited with her parents in Spain.
Authorities have not confirmed whether the victims in Tuesday's case were Leary and San Jose.
