A high school friend

I'm having a hard time wrapping my brain around a piece of information. While watching the news I learned that a high school friend of mine commit murder. Even writing those words makes me shake my head with disbelief. This was a person that I was close to. We spent countless hours together. We walked to school together every morning for years. We went to parties. We were friends. I don't know what happened since high school. Something changed. The murder was violent. It was intentional. My heart is so heavy. I don't know how to process this information. I've heard over the years of an ex-boyfriend who is now addicted to drugs. Though that bothered me I found I was able to deal with it. This... I don't know what to do. The night that I found out I couldn't even sleep. My mind was racing, playing out the whole scenario over and over again. Had this person not confessed I wouldn't believe it. All I can do to settle down the thoughts flying around my head is pray. For the families that were involved. For the friend behind bars. God bring healing.
