WASHINGTON - June 16, 2010 - A Northwest woman is devastated after she says her pet of 13 years was shot and killed by D.C. police.

Marietta Robinson, 62, is still visibly traumatized after witnessing her 13-year-old companion, Wrinkles, be shot and killed Tuesday night.

Robinson says the pitbull mix grew to be more than 100 pounds.

"I've had her since she was the size of my wrist... I still can't believe this," said Robinson.

According to the search warrant, six officers showed up at Robinson's door in the 1300 block 5th Street NW around 9:00 pm Tuesday in search of drugs and paraphrenalia in relation to her 28-year-old grandson.

Robinson says he hasn't lived in the home in years.

"My grandson couldn't even come in here 'cause he hasn't lived here so long. My dog don't know my grandson," said Robinson.

Robinson says she let them in under one condition.

"I said 'can I put my dog in the bathroom?'...The officer said 'yes' and then he opened the door and shot her," Robinson told us.

Bullet holes in the bathroom mark the spot where Wrinkles was killed.

"You can see all of the bullet holes, about eight bulletholes in this door. There is a bullet hole in the dryer..all up and down the steps. There's bullets everywhere," pointed out Robinson.
