Playboy model Christina Karlin-Craft’s boyfriend was questioned by police for several hours after she was found strangled in her luxury Philadelphia-area condo on August 22, Breaking Celebrity News can exclusively report.

The 36-year-old beauty’s longtime love Alex Ciccotelli Jr. spent the following day in the Lower Merion Township Police Department, his uncle David Ciccotelli told Breaking Celebrity News in an exclusive interview.

“The police were asking him questions,” David said.

But the elder Ciccotelli said he did not think cops were treating his grieving nephew as a suspect.

He called Karlin-Craft a “sweetheart” who got along well with her boyfriend’s family.

“She liked us, and she was just very, very nice,” David said. “I just can't believe this. She was a sweetheart. A total sweetheart."

Alex Jr.’s father, Alex. Sr, told Breaking Celebrity News the family is going through a “very stressful time” after the murder.

Cops did not respond to Breaking Celebrity News’s calls for comment about possible suspects in the case.

In a statement, the Montgomery County District Attorney’s Office told Breaking Celebrity News they were investigating the case, and the death was ruled a homicide by “ligature strangulation.”

"There has been no arrests in this case at this time,” Lower Merion Township Police Department spokesperson Michael McGrath told Breaking Celebrity News. “There is no update to provide at this time, but we encourage anyone that may have information that may be relevant to this case to contact our police department."
