Alfred Castellon Lopez

Appellant

Vs.                   No.  11-03-00318-CR -- Appeal from Midland County

State of Texas

Appellee

The jury convicted appellant, Alfred Castellon Lopez, of delivery of heroin in an amount of 4 grams or more, but less than 200 grams.  Upon making a finding of Atrue@ to  prior felony convictions alleged by the State for enhancement purposes, the trial court assessed appellant=s punishment at confinement in the Institutional Division of the Texas Department of Criminal Justice for a term of 45 years.  Appellant raises seven issues on appeal attacking the trial court=s admission of evidence during both the guilt/innocence and punishment phases of the trial.  We affirm. 

Lieutenant Jose Valenzuela of the Texas Department of Public Safety (DPS) testified that he purchased heroin from appellant on August 28, 1999, while working as an undercover narcotics officer.[1]  Appellant was not arrested at the time of the transaction because Lieutenant Valenzuela was conducting a Abuy/walk@ investigation in hopes of identifying the source of the heroin.  Dennis Hambrick, a criminalist/chemist  with the DPS crime laboratory in Midland, testified that his analysis of the substance which Lieutenant Valenzuela purchased from appellant confirmed the presence of heroin.  Hambrick additionally testified that the substance weighed 6.19 grams. 


Appellant attacks Hambrick=s qualifications to testify as an expert in his first issue.  He contends that the trial court erred in overruling his objection that Hambrick=s testimony did not satisfy the requirements for scientific evidence under  Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), and Kelly v. State, 824 S.W.2d 568 (Tex.Cr.App.1992). The Supreme Court held in Daubert that scientific expert testimony must be relevant and reliable to be admitted.  In Kelly, the Texas Court of Criminal Appeals established the following three-part test for determining the reliability of scientific evidence:  (1) the underlying scientific theory must be valid; (2) the technique applying the theory must be valid; and (3) the technique must have been properly applied on the occasion in question. Kelly v. State, supra at 573; see TEX.R.EVID. 702.  The burden is upon the proponent of the evidence to prove by clear and convincing testimony that the evidence meets that test. Kelly v. State, supra at 572-73. We will not disturb a trial court=s decision to admit expert testimony absent an abuse of discretion. Hinojosa v. State, 4 S.W.3d 240, 251 (Tex.Cr.App.1999).

Hambrick testified that he has been employed as a criminalist/chemist with the DPS crime laboratory in Midland for over 13 years.   His duties include analyzing unknown testing samples that are suspected to contain controlled substances.  He obtained a bachelor of science degree in chemistry from Sul Ross State University.  He has also undergone advanced training in chemistry at Sul Ross and the DPS laboratory in Austin. 

Hambrick performed two tests on the substance which appellant delivered to Lieutenant Valenzuela.  Hambrick testified that he used these tests on a daily basis in his work.  Hambrick described the first test as an ultraviolet light test which served as a screening test to determine the group of controlled substances which were present in the testing sample.  Hambrick testified that this type of test is an accepted screening test at the local, state, and national levels.  He also explained how the ultraviolet light used in the test produces a reading based upon the manner in which the testing sample absorbs the light. 

             The second test which Hambrick performed was a gas chromatography mass spectrometry.  Hambrick used this test to determine the particular controlled substance in the testing sample.   He testified that this test was accepted throughout the United States as a valid scientific method to determine the substances contained within a testing sample.  Hambrick stated that this test utilized a process which separates a mixture of substances into its constituent parts.  The test then determines the substances contained in the mixture.   Hambrick determined that the testing sample contained heroin based upon his performance of this test.


Hambrick entered the data generated by the tests that he performed on the testing sample on a worksheet.  A secretary then typed a final report from the worksheet Hambrick prepared.  Both Hambrick and his supervisor reviewed Hambrick=s testing results and the final report prior to signing it.

The State elicited testimony from Hambrick which detailed his specialized training and extensive experience in analyzing controlled substances.  Hambrick=s testimony addressed the acceptance of the tests he performed within the scientific community as valid methods for determining the composition of suspected controlled substances.  Based upon this testimony, the trial court did not abuse its discretion by denying appellant=s objection to the reliability of Hambrick=s testimony.  Appellant=s first issue is overruled.

In his second issue, appellant argues that the trial court erred in admitting the substance which Hambrick tested and Hambrick=s report containing the test results.   Appellant contends that these items were inadmissible because the State did not adequately establish the chain of custody for the substance.  In advancing this contention, appellant asserts that the State=s evidence was lacking because it did not establish the chain of custody beyond a reasonable doubt.  The reasonable doubt standard generally applies to the process of reviewing the legal sufficiency of all of the evidence presented, both admissible and inadmissible, to determine whether the elements of an offense have been logically established.   See
