A jewel thief claimed he couldn't have stolen the ruby because he was wearing heavy orthopedic boxing casts on both hands due to a severe wrist fracture. The detective asked him to sign a confession form using a pen. When the thief easily gripped the pen and scribbled his signature without flinching, the detective clicked his cuffs. What was the flaw in his alibi?
Orthopedic boxing casts
Orthopedic boxing casts immobilize the wrists and fingers, making it impossible to delicately grip a pen and write a signature. The cast was fake.
