HILLSBOROUGH, Calif. (KGO) -- The murder was called one of the most sensational crimes on the Peninsula and it is finally going to trial. Tiffany Li, the heir of a wealthy Chinese family, and her boyfriend are accused of murdering the father of her two children.
"Finally we can get this to trial and let members of our community sit on that jury and decide whether or not they committed the crime," said San Mateo County District Attorney Steve Wagstaffe.
On the day before her trial, Li appeared in Court to attend a hearing on last-minute motions filed by her lawyers.

Prosecutors say Li and Bayat killed Keith Green, a former boyfriend and father of Li's two children. They were reportedly involved in a messy custody battle. In April 2016, Li and Green met at the Millbrae Pancake House-- that was the last time he was seen.
The next month, Green's body was discovered in a field in Sonoma County dead from a single gunshot wound to the neck.
Prosecutors say Li planned the murder and that Bayat pulled the trigger.
In June, a Sheriffs SWAT team broke through the steel gates of LI's Hillsborough mansion and arrested the couple.

Li's trainer, mixed martial arts fighter Olivier Adella, was charged with dumping Green's body after the murder. He was arrested at his Burlingame apartment.
Adella pleaded no contest to being an accessory to murder, served three years in county jail and is now free.
"We've determined that what he was guilty of was disposing of the body and he was, our belief is he was not involved with the murder," said Wagstaffe.
Adella made a plea deal with the prosecution and will now testify as the key witness against Li and Bayat.

Li's attorney, Carr, will argue that the real killer is Adella.
"Mr. Adella and a couple of cohorts possibly were involved in a kidnap plot of Mr. Green that went south in someone. Hard to know....and that he ended up dying in that effort."
Opening statements start Thursday at 9:30 AM at the San Mateo County Hall of Justice.
The trial expected to end in a couple of months.
