Cookies For You

Two of six friends brought a plate of cookies for everyone to enjoy. They huddled together on the couch watching Home Alone. Within the next day, they were inside a hospital sick. The police came into the conclusion that someone injected poison inside of the cookies. One plate was poisoned. Here are their statements:

Ariel - I never bought any plate of cookies! Baleen is a liar!

Lillie - The plate of cookies are not mine! Clara is telling the truth!

Gabby - I love my friends! Why would I poison them with my cookies? I know for sure Ariel is a truthful person!

Clara - I had a plate of cookies, but why would I poison my friends? Gabby is always NOT true to her words!

Baleen - I didn't have the cookies, and I would of course know Lillie is a spittin liar!
