Prince George's County's Crossland High School has won an Interstate Mock Trial Tournament that involved more than 400 teams from New York state and Maryland.

Crossland, which earlier this month won the Maryland Mock Trial Competition, defeated Martin Van Buren High School from Queens, N.Y., to win the interstate title last week. The tournament was held at the U.S. Court of Appeals for the Second Circuit before Judge Ellsworth A. Van Graafeiland.

In the annual competitions, students play the roles of prosecutors, defense attorneys, researchers and witnesses and act out a hypothetical case before a judge, who scores them on the quality of the case they present and on their performances.

Crossland is coached by Robert Turner, social studies teacher coordinator at the school. Team members are Earl Bannister, Michael Bugg, Karen Gardener, Cathleen Gillen, Kenneth Kutsch, Veronica MacGalene, Brian Nagro, Keith Slydell, John Thomas and Joan West.

The hypothetical case used throughout the season by teams in Maryland and New York involved the question of whether evidence obtained in a drug purchase by an undercover police officer was admissible in court.

Last year, High Point High School, also from Prince George's, won the ruling in the interstate competition, but its opponent, Fayetteville-Manlius High School from Manlius, N.Y., received the higher score.

The interstate mock trial is sponsored by several groups, including the New York Bar Foundation and the Maryland State Bar Association.
