Five defendants are expected to face separate juries in first-degree murder trials by next week in a confluence of cases almost unheard of in any Massachusetts jurisdiction except Suffolk County, District Attorney Daniel F. Conley said today.

Suffolk Superior Court juries are already hearing evidence in the trials of ROBERT IACOVIELLO, Jr. (D.O.B. 6/19/87) of Revere, accused of fatally shooting off-duty Revere Police Officer Daniel Talbot in September 2007, and LARRY NELSON (D.O.B. 1/5/58) of Roxbury, charged with stabbing 64-year-old Richard Stroman to death in the victim’s Elm Hill avenue residence in October of the same year.

Assistant District Attorney Edmond Zabin, chief of Conley’s Homicide Unit, and Assistant District Attorney Edward Krippendorf are trying Iacoviello before Judge Patrick Brady in courtroom 815. Attorney Peter Krupp represents the defendant. Assistant District Attorney Gretchen Lundgren is trying Nelson with defense attorney John Palmer in courtroom 817. Judge Judith Fabricant is presiding over that case.

STEVEN ODEGARD (D.O.B. 8/5/67) of Dorchester is scheduled to face trial tomorrow, with jury selection slated to begin at 9:00 a.m. Odegard was indicted for the first-degree murder of 20-year-old Daniel Yakovleff, whose body was found repeatedly stabbed in Odegard’s bed on the morning of Jan. 17, 2008. Assistant District Attorney Mark Lee, deputy chief of the Homicide Unit, will the case with defense attorney John Swomley before Judge Regina Quinlan in courtroom 907.

Jury selection is expected to begin Monday for the trial of DA LIN HUANG (D.O.B. 3/16/63), formerly of Allston, who allegedly stabbed his wife, Gin Hua Xu, to death with a pair of pliers in their Cambridge Street apartment on Jan. 27, 2001. First Assistant District Attorney Josh Wall will try the case with defense attorney Larry Tipton in courtroom 808 before Judge Christine McEvoy.

On Jan. 27, attorneys will pick a jury for the double-murder trial of NICOLE CHUMINSKI (D.O.B. 5/19/82), charged with setting the fire that killed 14-year-old Acia Johnson and two-year-old Sophia Johnson in their West 6th Street home on the morning of April 6, 2008. Assistant District Attorney David Fredette of the Homicide Unit and Assistant District Attorney Julie Higgins of the Domestic Violence Unit will try the case with defense attorney William White before Judge Frank Gaziano in courtroom 906.

Suffolk County most recently hosted five concurrent homicide trials in early 2009, when violent deaths from 1990 through 2008 went to separate juries. Four ended in guilty verdicts; the fifth, a two defendant case, ended in a mistrial. Both defendants were subsequently convicted of first-degree murder at retrial.
