A registered sex offender from Windsor Locks will face the judge on Monday morning. 27-year-old William Leverett is charged with murdering insurance executive Melissa Milan in Simsbury nearly 4 years ago.

Law enforcement sources told the Courant that Leverett told officers he could no longer live with what he had done.

Leverett described what Millan was wearing the night of the attack and then brought police to where he had kept some items from that night.

It’s unclear what they were or where he had kept them. All of it was taken to the state police forensic laboratory for DNA testing.

Police say the attack appears to be random and Leverett lived just two miles from the crime scene.

Milan was a mother of two, and was vice president at Mass Mutual Life Insurance.

Leverett had never been arrested in the state before Sunday, but was arrested in Colorado 9 years ago charged with sexual assault of a child.

A statement released Monday by Millan’s family read:

The family, friends and coworkers of Melissa Millan are thankful for the outpouring of love and support we’ve received since Melissa’s death in November 2014. Melissa was a loving mother, a devoted daughter, a witty and compassionate sister, a loyal friend, an intelligent, successful businesswoman and 
mentor to many. The arrest and arraignment of the suspect brings renewed grief, heartache and the knowledge that justice can never be served for the senseless act that robbed us of Melissa’s beautiful presence. 

We extend our gratitude to the Simsbury Police Department and other participating law enforcement agencies for all of their work.  Now as we confront our individual and collective grief and sorrow, we humbly request respect for our privacy during this difficult and emotional time
