Officer Franklin is investigating theft of art from the local museum. Three people claim they were present when a woman wearing a smock rushed into the museum and snatched the van Gogh off the wall before running out a side exit. All three witnesses are at the police station and Officer Franklin has asked them to sit down with the police department sketch artist to help with his investigation. Together, the witnesses provide the artist with all the details they can recall, though there is some significant disagreement on some of the details. Officer Franklin uses the sketch on a wanted poster and Priscilla is identified by her neighbor, Molly, as matching the description. When she is brought in for questioning, Priscilla denies involvement in the crime and demands to have her attorney present. Priscilla refuses to participate in any lineup. The missing painting is not recovered, though a smock matching the description of the witnesses is recovered at her home.

Priscilla's attorney is moving to have the sketch suppressed as evidence against her client. What is the best approach to attack this evidence?

a. Witnesses should be separated to get an independent description of the suspect.
b. Wanted posters are notoriously inaccurate.
c. Molly has a grudge against Priscilla.
d. The van Gogh painting is still missing.
