OROVILLE, Calif. -

The trial of a Butte County man charged in the death of his pregnant girlfriend officially kicked off Monday morning.

Olabaku Jones was arrested in June of 2013 for allegedly beating Abby Tucker to death in their Oroville home.

The sheriff's office said Jones is a very violent man and is unpredictable when it comes to his behavior. They asked the judge if he would remain in soft restraints for everyone's safety.

Jones walked into the courtroom shackled with three deputies watching him at all times.

Normally during a trial, the defendant is not handcuffed and not dressed in the typical orange jump suit if they are in custody. This helps the jury to not be biased towards the defendant.

However, deputies said with Jones' behavior, it's best for him to be handcuffed. The judge agreed.

Deputies testified Jones attacks the guards while they are moving him throughout the jail, he destroyed a fire sprinkler in his cell and caused it to flood, and they need more guards to get him out of his cell to come to court.

For the trial, they'll be covering his arms and legs with a black cloth at the end of the table so the jury can't see it.

The prosecution did offer Jones a deal to plead guilty to a second degree murder charge where he would serve 15-years-to-life in prison. Jones decided not to take that deal.

A jury was selected Monday and the trial continues on Thursday. Jones is facing 59-years-to-life in prison.
