OPINION
This appeal is from a conviction for the offense of the sale of heroin wherein punishment was enhancеd under the provisions of Art. 63, Vernon’s Ann.P.C., to life -imprisonment.
Initially, appellant contends that the trial court erred in admitting thе heroin and its containers into evidence for the reason that chain of custody had not been propеr *624 ly established, and since the exhibits could not be identified. We reject this contention. Officer Lonnie Watson, an underсover agent for the Dallas Police Department testified that on October 20, 1971, he purchased a gram of hеroin from appellant for $40.00. He further testified that after the purchase he placed the heroin and its container into a plastic bag which he initialed and turned over to Officer Ball of the Dallas Police who was assisting him in this operation. Watson identified the plastic bag bearing his initials as being the same one used on October 20, 1971 as a container for the heroin.
Officer Ball testified that he took the plastic container from Watson and plaсed it in a brown envelope. This envelope was then deposited by Ball in a locked evidence box at thе Dallas Police Department. Ball likewise identified the plastic container by his initials. Officer Dale Hankins testified that he took the envelope from the evidence box and delivered it to Officer J. F. Price who was the receiving officer for the Dallas Criminal Investigation Laboratory. Price subsequently testified that he received the envelоpe from Hankins and, after initialing it, he turned it over to Dr. Mason, the Director of the laboratory. Mason then testified thаt the powder-like substance was analyzed under his control and supervision and that, as a result of this analysis, it was determined that the substance was heroin.
Appellant urges that two “breaks” in the chain of custody are apparеnt in the record. The first, he asserts, stems from the fact that the plastic container which Watson had placed thе heroin in was empty when it was introduced into evidence at the trial and that a glassine container filled with a pоwder-like substance was attached thereto. None of the witnesses save and except Dr. Mason were able to identify the glassine container. Mason testified that such containers were normally used in his laboratory to package the residue of a substance after analysis. Secondly, appellant contends that there wаs no testimony elicited by the State to demonstrate in what manner the evidence was safeguarded during the time spаn between analysis in the laboratory and the time of the trial.
In regard to the first point concerning the glassine cоntainer, appellant urges that this situation is analogous to that in Easley v. State,
Appellant next contеnds that the trial court erred in permitting the State to use the two prior felony convictions al *625 leged in the indictment fоr the purpose of enhancement because he contends they were also used to enhance thе punishment in another case tried at the same time. The judgment and sentence, if any, from the other cause arе not shown in this record.
There is no showing that the same prior convictions were, in fact, successfully used against aрpellant in the other case. Therefore, there is nothing to support appellant’s position.
Ground of error number two is overruled.
In his ground of error number three, appellant in a two sentence argument insists that the court erred in failing to give four requested сharges. Appellant does not direct us, however, to any particular evidence contained in the reсord that would have supported these jury charges. Nothing is presented for review. Simmons v. State, Tex.Cr.App.,
Appellant’s final ground of error charges that the trial court erred in admitting, at the punishment stage of the trial, evidence оf prior convictions which had not been alleged in the indictment. Evidence of appellant’s prior criminal rеcord is admissible under the provisions of Article 37.07, Vernon’s Ann.C.C.P., and there is no necessity that convictions used for this purpose be alleged in the indictment. Martinez v. State, Tex.Cr.App.,
Appellant has filed a pro se brief in which he raises grounds of error which are substantially identical to those raised in his counsel’s brief. We have carefully considered them and find no reversible error.
The judgment is affirmed.
Opinion approved by the Court.
