 Update: Warrant describes a brutal, unprovoked attack in 2014 stabbing death of Simsbury jogger Melissa Millan » 
  
 William Winters Leverett, 27, of 11 Seymour Road Unit 11A, walked into Simsbury police headquarters Wednesday night and confessed, later leading police to a hiding spot where he had kept some items he had taken from the scene, law enforcement sources told The Courant. Police charged him Sunday.

 The attack, sources said, appears to have been random. It shocked the quiet community and stymied investigators for years. 
  
 Leverett had been convicted of sexual assault in the fourth degree in Colorado, moved to Simsbury in 2011 and lived on Goodrich Road, less than two miles from where the slaying occurred on Iron House Boulevard. He registered in Connecticut as a sex offender when he moved to the state, authorities said. 
  
 He re-registered with Connecticut State Police last week and listed Seymour Road in Windsor Locks as his address. He worked at The Fresh Market in Avon as an assistant manager. The store issued a statement Monday saying it was cooperating with the investigation and was sending its sympathies to Millan’s family and the community. 
  
 His mother, Sarah Leverett, broke down in tears at her Colorado Springs home when told Sunday that her son had confessed to the Connecticut killing. She said she hadn't known about her son turning himself in, before declining to say more. 
  
 The state police were called in Thursday to assist in investigating the details of Leverett’s confession. Sources said Leverett described what Millan was wearing the night of the attack and then brought them to where he had kept some items. It’s unclear what those items were or where he kept them. 
  
 The items were taken to the state police forensic laboratory for DNA testing. 
  
 Leverett will be arraigned in Superior Court in Enfield on Monday, police said. The arrest warrant was sealed pending his arraignment. 
  
 Millan, 54, a senior vice president at Massachusetts Mutual Life Insurance Co., was running along a trail that cuts behind the center of town on Nov. 20, 2014, when she was stabbed in the chest. The weapon wasn’t recovered. 
  
 Police believe the killing occurred between 7:30 p.m. and 8 p.m. There were no witnesses who came forward. 
  
 Six months after Millan was found dead, an anonymous donor put forth $40,000 as a reward for information leading to the arrest of the killer. At the time, police said they had no suspects and were actively looking for leads. 
  
 Leverett was arrested in Colorado in 2009 and charged with sexual assault of a child, according to police records. He pleaded guilty in 2010 and was fined $438. He received no jail time. He was put on probation, placed on the sex offender registry list and ordered to give a DNA sample to Colorado officials. 
  
 The El Paso County Sheriff’s Department declined to release any records concerning his case to The Courant on Friday. Leverett had never been arrested in Connecticut before Sunday. 
  
 The FBI and the Connecticut chief state’s attorney’s office cold case squad got involved in the investigation more than a year ago. Investigators went back out to the area last November and conducted a new search for evidence. 
  
 But the case appeared stalled until Leverett walked through the doors of the Simsbury police headquarters with members of a religious institution. Sources said Leverett told officers that first night that he no longer could live with what he had done.

Output:
Almost four years after insurance exec Melissa Millan was fatally stabbed on a Connecticut jogging trail, a suspect walked into a police station and confessed to the killing, law enforcement sources say. William Winters Leverett, 27, has been charged with murder and will appear in court Monday, police in Simsbury said in a press release. Police sources tell the Hartford Courant that Leverett, who arrived at the station accompanied by members of his church last week, said he could no longer live with what he had done. The sources say Leverett led police to where he had stashed items he had kept from the crime scene after what was apparently a random attack. Millan, the 54-year-old mother of two children, was stabbed in the chest on a popular hiking trail on the evening of Nov. 20, 2014. Police said six months later, when an anonymous donor offered a $40,000 reward, that they had no suspects. Leverett's landlord, Brian Durso, tells WFSB that Leverett couldn't live with himself any longer. "This young man went to the leaders of the church that I had been associated with and he was, and they made a decision after I think a lot of (tears) and prayer to go to the authorities," he says. Leverett is a registered sex offender who was convicted of sexual assault on a child in Colorado in 2011. He moved to Connecticut the same year.
