Memo to self: don't buy new bedding after killing spouse

Am I missing something? An American woman in Hong Kong killed her husband with a combo poison milkshake and blunt object over the head, and then goes out and buys all new bedding, telling her maid not to clean the bedroom.

...the day after the alleged killing, Nancy Kissel went on a shopping spree, buying a bed, sheets and a carpet. She also told her Filipino maid not to clean the master bedroom, the prosecutor said.

Three days after the alleged killing, the wife asked maintenance workers at her apartment complex to help her haul a thick roll of carpet to a storage area, Chapman said. When the maid noted that the roll seemed unusually bulky, the wife said it contained pillows and blankets, the prosecutor said.

The workers who moved the carpet said it smelled like rotting fish, Chapman said.

Now that's bold. It's one thing to have an affair and then kill your husband, but to then ask the apartment maintenance guys to carry out the body for you is not going to go over well with the jury. But why does everyone immediately buy new bedding after killing someone? Don't they know it's a dead giveaway (pardon the pun)?

No word yet if the husband's estate will attempt to sue McDonald's for the tainted shake not having a tight enough lid.
