Police say a Texas woman attempted to hide evidence during an arrest by defecating in her pants and using the feces to conceal drugs.

Officers in Corsicana, about 55 miles (88 kilometers ) south of Dallas, were investigating a report of a theft at a grocery store on Wednesday when they attempted to subdue a female suspect and take her into custody.

Police say they placed Shannen Martin in the back of a police cruiser where they say she intentionally defecated in her pants then hid a crack pipe, 2.3 grams of crack cocaine and a Valentine's Day card in her excrement.

Officers had to sift through the woman's feces to retrieve the evidence after Martin was booked on charges of tampering with evidence and possession of a controlled substance.
