Police chased him for about 20 minutes, but the pursuit ended when Wilcher hit another car.
Family members, their pastor and a bail bondsman said they've been trying to see Wilcher since his arrest but have been denied or redirected.
They said they just want to know he's alive.
"Where is my child? I need to know. This had happened yesterday and I have not heard a thing. They keep telling me that he has minor injuries. So where is my child? Where is my son? I need to see him. I need to know that he's OK," said the suspect's mother, Linda Wilcher who said her son has been diagnosed with bipolar schizophrenia.
The LAPD has not responded to those claims but says it is monitoring the situation.
