The petition was closed Sunday after Walmart released a statement disavowing the costume makeup and pulled it from its online listings.
According to Walmart, the costume was listed on its website by a third-party seller.
"The costume is appalling and it was unacceptable for a third-party seller to list it on our marketplace," Walmart employees said in a statement released to WABC. "It clearly violated our prohibited items policy and we removed it yesterday morning when it was brought to our attention."
WABC identified the third-party seller as BlockBuster Costumes LLC. In a statement on the company's Facebook page, BlockBuster Costumes announced it had taken the offending costume makeup off its website.
"To those contacting us about our suicide costume we've removed the offending product from our site," according to a post made Monday. "It shouldn't have been marketed as such."
