Real Housewives of New York star Bethenny Frankel says she wants to take in a 5-year-old girl who was abandoned at a New York bus terminal on Monday.

Frankel, 46, took to Twitter on Tuesday to tweet an article about the abandoned little girl, writing, “How do I adopt this child?”

And now a friend of the star tells PEOPLE that Frankel is “definitely serious about it.”

Police found the little girl on the second-floor concourse of the Port Authority Bus Terminal Monday morning and took her to the police station where they determined that a man believed to be her father allegedly left her there, a spokesman with the Stamford, Connecticut, Police Department confirms to PEOPLE.

“Right before he abandoned her, he told her to wait for him — that he’d come back. And he did not, in fact, come back,” the spokesman says.

The child was able to tell investigators where she lived and no one answered the door at her Courtland Avenue home in Stamford, Connecticut, when they arrived, the spokesman says.

“They went in to find the young child’s mother deceased in a bedroom at that location,” he tells PEOPLE.

Officials said that the girl was unharmed and is Connecticut state custody.

Police are now searching for 32-year-old Elmer Gomez Ruono, who was allegedly seen on surveillance footage leaving the child at the bus terminal at around 8:30 a.m. – just 90 minutes before the girl was found.

The spokesman says that Ruono is a person of interest in the investigation. He says the mother’s death has been ruled a homicide.

After her initial post, Frankel sent out a pair of tweets regarding adoption.

“Lawyer says once [with] the state a private adoption impossible which is now upsetting me more,” she wrote. She added in another post, “There’s a misconception that everyone wants an infant. Bc of this rule, babies [are] the only option. Once in the system kids [are] lost. Sad.”
