Can you be charged with burglary if there was no fingerprints or any investagation taken?

I was charged with burglary, attempted burglary, and illegal consumption because one night, I was intoxicated and I was outside of a friends apartment complex. An older gentleman called the police saying he thought he saw me breaking into cars. The police got there and immediately gave me a blood alcohol content test and it was .221. I don't remember what happened that night because I blacked out. I woke up in the police station and the next thing I know they were transporting me to judicial district court. They didn't take fingerprints or do any sort of investigation and I don't know what happened in the police station. All I know is I had a bruise on my arm and my neck after I came to in the police station. What is the best thing I should do about this?
