Crimescene

From BoardGameGeek:

Crimescene is a simple drawing and deduction party game. At the start of the game, two teams of witnesses are given their 'crime scene' - an animal, a place, a school subject, etc - which only they know but which their detective must guess. Teams take turns selecting from a grid of 25 random transparent cards (clues) with preprinted graphics. They can then use dry-erase markers to draw additions to their clue before placing it onto their detective's investigation sketchboard, painting a picture of their crime scene. The team whose detective correctly guesses their crime scene from their investigation sketchboard first, wins the game. Watch out though, as opposing witnesses and detectives have ways to keep your mouth shut! -description from the designer
