Seattle Police are looking for a person suspected of tampering with evidence at a police impound lot.
A man and a woman ended up there after the trailer they were living in was accidently towed to the lot.
The couple tried to hide after they were spotted and left a big mess behind.
"Saw the nearest fire extinguisher and unloaded it, thinking it would hide their identities... it did not,” said police spokesman Sean Whitcomb.
The woman was caught and taken into custody but the man she was with is still on the loose.
Police are investigating whether the couple may have tampered with evidence from as many as 10 different cases.
