Monica Sementilli says she did not help plan the murder of her LA beauty exec husband. Will a jury believe her?

In 2017, Monica Sementilli had an enviable life — a luxurious house with a pool and a Porsche in the driveway — in a posh area of Los Angeles.

But after spending almost seven years behind bars waiting through legal delays and COVID, she is scheduled to go on trial for the murder of her husband, celebrity hairdresser and beauty executive Fabio Sementilli.

As "48 Hours" contributor Michelle Miller reports, it's a tangled story. Her defenders say Monica Sementilli is an innocent victim. But if you believe prosecutors, she's a criminal. Authorities describe a case of lust, greed, and murder. Whichever it is, the drama unfolded on Jan. 23, 2017.
