A Harlingen mother pleads for the public's help to find her son who vanished shortly after being released from the East Campus of Valley Baptist Medical Center in Brownsville.
It has been a week since 42-year-old Ricardo Zamora went missing.
Zamora suffers from bipolar disorder, schizophrenia and thyroid.
His mother, Graciela Martinez, said he is in desperate need of his medication.
His medicine is his life, it's for him to survive his disease, Martinez said.
Last Wednesday, when Zamora was released from the Valley Medical Center he was put in a cab, something that had been done before without any problems.
However, this time Zamora did not arrive.
Harlingen police said the Yellow Taxi Cab Company log shows Zamora was dropped off in Harlingen but the driver later told investigators he actually left the man in the HEB on Paredes Line Road in Brownsville.
Family members and friends have been posting missing signs.
They have searched the areas of Harlingen, Brownsville and even Matamoros but still no leads.
Martinez said one thing she has learned from this whole experience is that policies for transporting patients should change.
What I plan to do is for this to change, Martinez said. This can't happen to anyone else because this is negligence.
Action 4 News and Martinez tried speaking with the taxi cab company but they refuse to return the calls.
If you see Zamora, contact the Harlingen Police Department at (956) 427-8787or Brownsville Police Department at (956) 548-7000.
