The 24-year-old disappeared September 17. The Cal State Fullerton graduate was arrested at Geoffrey's, a high end restaurant in Malibu, because she did not have the money to pay for her bill. Other diners and restaurant staff said Richardson was acting in bizarre manner.
Looking back, family members say they now realize Mitrice was in the midst of a mental breakdown.
Richardson was booked at the Lost Hills/Malibu Sheriff's Station. Deputies said Richardson acted normally and passed a sobriety test and had no reason to hold her overnight. She was released at 12:30 a.m. but had no car, cell phone, identification or money.
The next morning, a woman fitting her description was spotted in Monte Nido, a rural community in Malibu Canyon six miles away from the sheriff's station.
In the six months since Richardson disappeared, there have been several large-scale searches including one in January that involved hundreds of law enforcement personnel and volunteers.
On Sunday, family members and friends will hold an all volunteer search.
"If you're a hiker, we'd love for you to take a hike and look in these canyons and see if you find anything that may help us," said Sutton.
The volunteer search is from noon to 4 p.m. in six different locations around the Los Angeles area.
