The appellant was indicted for manslaughter, in violation of §
The driver of the trash truck testified that from his experience in having observed cars and trucks in motion and having driven automobiles, he estimated the speed of the Toyota at approximately 70 miles per hour. Thereafter, a police officer who investigated the scene of the accident testified that he had investigated several hundred accidents. He stated that he had attended schools on the investigation of traffic accidents, including the Institute of Traffic of Northwestern University in Illinois, an advanced accident investigation course in Jacksonville, Florida, with the Institute of Police Technology and Management, and a course on accident reconstruction in Jacksonville, Florida with the Institute of Police Technology and Management. He testified that, during these courses, he was taught how to calculate the *538 speed of an automobile at the time of a collision and what factors or evidence on which to concentrate in determining speed. The officer testified to the specifics of his information gathering in the present accident, the measurements he made, and the photographs he observed. Generally, the formula which the officer used involved determining the weights of the two vehicles, determining the coefficient of friction of the road, and determining the distance which the truck was moved by the impact. The officer testified that this method has been accepted and used in the investigative community and that its reliability has been established. The officer concluded that the appellant's vehicle must have been traveling at approximately 56 to 61 miles per hour at the time of impact.
The appellant argues that the officer should not have been allowed to give his opinion as to the speed of the vehicle, because, he argues a proper predicate was not laid for the admission of such testimony. The leading case concerning expert testimony as to the estimated speed of an automobile at impact is Maslankowski v. Beam,
The trial court did not abuse its discretion in allowing the officer to testify to his calculations concerning the speed of the appellant's automobile. As the Court stated inMaslankowski:
"This Court does not wish to be understood as holding that in all cases of automobile collision such evidence by any self-proclaimed expert is admissible, but as in every civil case where expert testimony is presented, the responsibility is on the trial court to satisfy itself of the requirements of the law regarding admissibility. If the responsibility is exercised with care so that reasonable expert testimony is presented based upon reasonably sound scientific approaches, then this Court will not reverse in the absence of an abuse of discretion."
The father's refusal to allow his son to take the test was properly admitted for the jury's consideration, as it was relevant toward the determination of whether the appellant was under the influence at the time of the accident. The test of relevancy in Alabama is liberal and "a fact is admissible if it has any probative value, however slight, upon a matter in the case." C. *539 Gamble, McElroy's Alabama Evidence, § 21.01(1) (3rd ed. 1977). Relevancy is distinguishable from weight or proof. 1A Wigmore,Evidence § 29 (Tiller's rev. 1983).
Id."[J]udges constantly find it necessary to warn us that their function in determining relevancy is not that of final arbiters but merely of preliminary testers; the evidentiary fact offered does not need to have strong, full, superlative, and probative value and does not need to involve demonstration or to produce persuasion by its sole and intrinsic force but merely needs to be worth consideration by the jury. It is for the jury to give the fact the appropriate weight in effecting persuasion."
The father's refusal was admissible because the State proved its relevancy. The refusal was in the nature of a tacit admission by the defendant. C. Gamble, McElroy's AlabamaEvidence § 193.01 (3rd ed. 1977). Contrary to the defendant's argument on appeal, there was evidence that the defendant was conscious when the tests were requested to and capable of responding to the request. Additionally, there was evidence that the father had observed and talked to his son before he refused to allow the tests to be performed.
There is a logical relationship between the father's refusal to allow his son to take the test and the ultimate inference that his son was under the influence. Therefore, the testimony was relevant and properly placed before the jury for its determination of how much weight to accord the evidence. We find no abuse of discretion by the trial court in allowing the testimony into evidence.
There was evidence that the trash vehicle's hazard lights were functioning on the day of the accident, and a police officer testified that they were visible from behind the trash vehicle. Any repair or alteration in the lighting of City trash trucks was irrelevant in the present case. The negligence of the owner or driver of the trash vehicle is not in issue. The appellant was convicted of homicide by vehicle, in violation of §
"Whoever shall unlawfully and unintentionally cause the death of another person while engaged in the violation of *540 any State law or municipal ordinance applying to the operation or use of a vehicle or to the regulation of traffic shall be guilty of homicide when such violation is the proximate cause of said death."
Thus, the State must have shown the appellant unintentionally caused the death of someone else while violating a traffic or vehicular law or ordinance. In the present case, the State introduced evidence that the appellant was speeding and operating his vehicle in a reckless manner. There was also evidence that the appellant was driving under the influence. Both of the passengers in the appellant's car were killed as a result of the appellant's crashing into the back of the trash vehicle. The accident took place at approximately 1:00 p.m. Because any changes made to the lighting on City trash vehicles was irrelevant in the instant case, the trial court properly disallowed the evidence.
