Replying to HELP!!!!!

I went to a party Saturday night (the 7th). Attendees were 17-19 years old. There was plenty of booze and weed there, as normal. In the morning, the host of the party found out that someone had stolen a TV, Wii, and box of jewelry from the house at some point during the night. She called the police and reported it. Now I'm pretty certain they will come to interview me about it. I am wondering if it's in my best interest to tell them the truth about everything that happened (including that I consumed both alcohol and weed), or try to make up another story?
I'm not sure if lying to police in this case constitutes interfering with a police operation, which is illegal?
Just for the record, I did not steal anything.
