SC20193 - State v. Jackson (Murder; conspiracy to commit murder; assault first degree; certification from Appellate Court; whether Appellate Court incorrectly concluded that trial court had not abused its discretion when it allowed state's belatedly disclosed expert witness on cell site location information to testify without first granting defense reasonable continuance to obtain its own expert; "The defendant, Raashon Jackson, appeals from the Appellate Court's judgment affirming his conviction of one count of murder in violation of General Statutes § 53a-54a (a), one count of conspiracy to commit murder in violation of General Statutes §§ 53a-48 (a) and 53a-54a (a), and four counts of assault in the first degree in violation of General Statutes § 53a-59 (a) (5). See State v. Jackson, 183 Conn. App. 623, 627, 193 A.3d 585 (2018). The defendant claims, among other things, that it was an abuse of discretion for the trial court to permit the state's expert witness on cell site location information (CSLI) to testify as to what that information revealed about the location of the defendant and his associates during the time the crimes occurred because the state disclosed the expert after voir dire began and only one week before evidence started, despite a court order issued six months earlier requiring the state to disclose any experts. Alternatively, the defendant argues that it was an abuse of discretion for the trial court to deny his related motion for a continuance to obtain his own CSLI expert. We conclude that it was an abuse of discretion for the trial court to allow the state's late disclosed expert witness to testify without first granting the defendant a reasonable continuance to obtain his own expert. Because we also conclude that this error was harmful, we reverse the judgment of the Appellate Court.")
