Opinion

Opinion by

Judge RULAND.

Defendant, James Stewart Genrich, appeals from the judgments of conviction entered upon jury verdicts finding him guilty of *801 three counts of use of explosives to commit a felony, third degree assault, and two counts of extreme indifference homicide. We affirm.

Defendant’s convictions arose.out of three different incidents in which pipe bombs exploded and injured one victim and killed two other victims. After a lengthy and extensive investigation that included various suspects, law enforcement officers focused on defendant and he was ultimately charged. The investigating officers included both .local police officers and agents of the Federal Bureau of Alcohol, Tobacco, and Firearms (BATF).

I

Defendant first contends that the trial court committed a gross abuse of discretion in not conducting a hearing in advance of the trial to determine whether the toolmark identification testimony offered by the prosecution was sufficiently reliable to warrant admission in evidence. According to defendant, a pretrial hearing was required regardless whether CRE 702 or the test established in Frye v. United States, 293 F. 1013 (D.C.Cir.1923), governed admission of this evidence. We find no error.

The challenged evidence consists of testimony from a BATF expert that three different sets of pliers recovered from defendant were used in making one or more of the bombs. According to this witness, one set of defendant’s pliers was used to cut certain wire, the wire strippers were used to cut a different wire, and a third was used to fasten a cap to the pipe. The witness also testified that wires used in two of the bombs came from the same batch of wire.

In the initial pretrial motion challenging this testimony, defendant contended that the evidence was not based on a theory generally accepted in the scientific community, that no techniques in the examination were capable of producing reliable results, and that the prosecution’s expert did not use tests that followed accepted scientific techniques. Accordingly, defendant contended that the testimony was inadmissible under the test first enunciated in Frye v. United States, supra.

See Fishback v. People, 851 P.2d 884 (Colo. 1993){Frye test is applicable in determining admissibility of novel scientific evidence).

In response to this motion, the prosecution offered to prove that toolmark identification evidence had been accepted in a number of courts throughout the United States over an extended period of time. The prosecution relied upon citations to various appellate court decisions. On this basis, the prosecution contended that an evidentiary hearing was unnecessary. Defendant did not offer testimony or legal authority at the hearing to contradict the prosecution’s position or otherwise to support the allegations in his motion.

The court ruled that, based upon these submissions, it appeared that the Frye test applied. It further concluded that defendant had failed to demonstrate a lack of general acceptance in the scientific community of the principles employed by the expert. Accordingly, the court denied the motion.

Defendant made a subsequent motion during trial for a hearing to determine whether the evidence should be admitted. In this motion, defendant argued that CRE 702 applied. The court also denied this motion.

In support of his argument on appeal, defendant notes that the BATF agent who served as the prosecution’s expert did not have any post-high school formal education. Defendant also points out that no standard curriculum has been developed to train tool-mark examiners and that no national certification program is available to confirm the knowledge and training of this type of expert.

Defendant further notes that, unlike fingerprint or ballistics testing, no data bank has been established relative to the various types of handtools. Conversely, defendant complains that the expert’s testimony relative to the examination of only two consecutively manufactured tools is insufficient to support his claim that every tool leaves a mark or marks different from every other tool.

Finally, defendant relies upon the potential rate of error suggested by the record before us. For example, two additional toolmark and firearms examiners were called in by the *802 prosecution to review the tests and analysis conducted by the BATF agent. With reference to the three sets of pliers, these experts agreed with the agent as to the marks from one set but they determined that the tests were inconclusive as to the other two. As a result, defendant asserts that the prosecution has not been required to demonstrate properly the reliability of this type of evidence. We find no error in the court’s rulings.

The prosecution’s expert had been employed in law enforcement for approximately 30 years, including six years with the BATF. The witness testified as to his on-the-job training as a firearms and toolmark examiner and he indicated that he had testified in excess of 400 times as an expert. While the majority of this expert testimony had involved firearms, a significant part involved toolmarks.

The record reflects that the basic premise for toolmark analysis is that handtools used either to cut or to clamp softer materials may leave a specific and essentially permanent type of mark on that material. The softer material is examined under a microscope that magnifies the marks to 80 times their original size. The handtool can then be examined to determine whether the marks were left by that specific tool.

According to this expert, no two tools make exactly the same mark on softer material either because of the manufacturing process or because of the subsequent use or misuse of the tool. In this regard, the witness stated that he had never encountered any research or other data indicating that any two handtools of the same type can make the same mark.

Legal research reflects that experts in the use and analysis of tools have long been permitted to testify concerning the marks left by those instruments. See State v. Baldwin, 36 Kan. 1, 12 P. 318 (1886)(experienced carpenters permitted to testify that wood panel could have been cut by defendant’s knife); see also A. Moenssens & F. Inbau, Scientific Evidence in Criminal Cases § 4.24 (2d ed.1978). Also, this testimony has addressed a number of different types of tools. See State v. Olsen, 212 Or. 191, 317 P.2d 938 (1957)(hammers); State v. Raines, 29 N.C.App. 303, 224 S.E.2d 232 (1976)(crowbar); State v. Wessling, 260 Iowa 1244, 150 N.W.2d 301 (1967)(serewdriver); State v. Churchill, 231 Kan. 408, 646 P.2d 1049 (1982)(knives).
