DWI trial on Oct. 4. Blood evidence suppressed on facts nearly identical to 315 S.W.3d 660. Affidavit failed to state the time when D was suspected of operating vehicle while intox.

I'm prosecuting it on HGN and refusal of everything else.

Can anyone recommend an HGN expert (preferably in the Houston area)who can testify on the SCIENCE of HGN?

Thanks in advance.
