  • State of Texas v. F.K.

    Practice Area:
    DUI & DWI
    Date:
    Dec 11, 2009
    Outcome:
    Not Guilty
    Description:
    Client was pulled over by a fire truck for almost striking the truck at 330am. SFSTs at scene from DWI Task Force. Client blew a 0.16 Breath Test at the station. Client was an international oil man and travelled all over the world. A DWI would have prohibited him from entering Canada and other countries. We had to win. Hired a language expert and co-counsel. I have a picture of all of us smiling in front of the court after hearing those two beautiful words: Not Guilty! We still keep in touch.

    Outcome:
    Not Guilty
    Description:
    Client almost hit a sidewalk and bushes as he squeeled around a corner. Pulled over and was too incoherent to answer any questions or walk. Carried to the patrol car and carried into jail. No scene video. Station video of him replying "nah" to every question and barely standing up. 2nd DWI within 5 years so had a minimum of 5 days in jail if we lost. Prominent Houston family, we didn't have the option of losing. The jury said "the State failed to prove the case beyond a reasonable doubt." The jury followed the law.

    Feb 05, 2010

    Not Guilty
    Description:
    Client left a bar on Washington at 2 a.m. Pulled over for speeding and weaving. Pulled over by DWI Task force including the Sgt of the Task Force. Failed the HGN, Walk and Turn and OLS. No breath test. Full scene video of all tests. Jury did the right thing and followed the law: State could not prove it beyond a reasonable doubt. Didn't help the State that the DWI Officer was one of the worst I have ever seen and was caught lying on several cases. We just can't have that on the force.
  • State of Texas v. E.O.

    Practice Area:
    DUI & DWI
    Date:
    Feb 08, 2010
    Outcome:
    Not Guilty
    Description:
    Client was driving home from a bar and pulled over for weaving and speeding. HGN 6 clues and almost hopped into traffic on the One Leg Stand. Donkey hee-hawed in the middle of it forcing client to laugh uncontrollably. Prosecutor wouldn't reduce the case. We had nothing to lose. As in most 1st DWIs, you'll still get probation even if you lose at trial. Why take the strike without even swinging the bat? Client still can't believe how far we hit that HOMERUN! We still keep in touch and thank the lord the jury followed the law.
