expert giv<strong>in</strong>g an op<strong>in</strong>ion based upon factual assumptions, the validity of which are for the<br />
jury to determ<strong>in</strong>e. The former is manifestly improper, the latter is not”). While “[r]elevant<br />
testimony from a qualified expert is admissible only if the expert knows of facts which<br />
enable him to express a reasonably accurate conclusion as opposed to conjecture or<br />
speculation[,]” Jones v. Otis Elevator Co., 861 F.2d 655, 662 (11th Cir. 1988), “absolute<br />
certa<strong>in</strong>ty is not required. Expert testimony is admissible which connects conditions exist<strong>in</strong>g<br />
later to those exist<strong>in</strong>g earlier provided the connection is concluded logically.” Id.<br />
Defendant argues that Dr. Warren’s testimony is not helpful to the jury because it<br />
merely recites the circumstances of Mr. Moncrieffe’s <strong>in</strong>jury and misleads the jury by<br />
suggest<strong>in</strong>g that the expert was present when the <strong>in</strong>cident occurred. Defendant’s attempt<br />
to exclude the testimony by argu<strong>in</strong>g that the jury will be mislead is wholly without merit: Dr.<br />
Warren can be asked, dur<strong>in</strong>g cross-exam<strong>in</strong>ation, whether he was present and can be<br />
impeached if he does not answer truthfully. In addition, Dr. Warren is not go<strong>in</strong>g to merely<br />
recite the circumstances of the accident. While he will base his op<strong>in</strong>ion, <strong>in</strong> part, on the<br />
testimony of Mr. Moncrieffe and Mr. Pedro Diaz, one of the two <strong>in</strong>dividuals who first<br />
responded to the scene, he is also go<strong>in</strong>g to testify about applicable ISO and other safety<br />
standards, and about an alternative design which, <strong>in</strong> his expert op<strong>in</strong>ion, would have<br />
prevented the <strong>in</strong>juries.<br />
Moreover, Dr. Warren is not be<strong>in</strong>g offered as a reconstruction expert and is not<br />
expected to testify as to how the accident happened. While the series of events as<br />
described by Mr. Moncrieffe and other witnesses offered by Pla<strong>in</strong>tiffs is at odds with<br />
Defendant’s version, there is support <strong>in</strong> the record for Dr. Warren’s factual assumptions.<br />
For these reasons, I conclude that Dr. Warren’s expert testimony will assist the jury.<br />
