A man who said he strangled a newlywed and then set fire to her home has been sentenced to 4-12 years in prison.

Christopher Bayer pleaded guilty in Suffolk County Court last month to manslaughter and arson charges, admitting he strangled 20-year-old Laura Giampino during what he described as consensual rough sex in her Ronkonkoma home last May. Bayer also said he set fire to the house and fled in a panic.

An autopsy found Giampino died from strangulation. Relatives of the victim dispute the sex was consensual and claim she was raped before being killed. She had been married five months when she died.
