Maine authorities have provided more details about a Sabattus shooting that left three people dead and two people injured late Wednesday afternoon. James Davis III, 29, of Sabattus, has been identified as the shooter. Maine State Police Col. William Ross said Davis was experiencing a mental health crisis before the incident, which resulted in the deaths of the suspect’s mother and a woman who worked at two elementary schools in the area. Here is what we know after a news conference that was held by public safety officials Thursday afternoon. What we know about shooter Davis lived with his mother, 47-year-old Christine Smith, at a home on Dube Drive, according to Ross. The residence is less than a mile from where the shooting took place. Ross said Davis did not have a driver’s license and his work history was “sporadic,” and described him as someone who is very localized. Smith was described by Ross as Davis’ primary caregiver. Davis visited his father before the shooting Ross said Davis visited with multiple family members at his father’s house on Birchwood Drive, where his grandmother also lives, and spent the majority of the day there. According to Ross, investigators believe Davis was driven to his father’s home by his mother Wednesday morning. Shooter’s behavior before incident Ross said family members told police that Davis started a mental health crisis during his visit, as he was acting erratically and saying things that did not make sense. According to Ross, there was no indication from family members that Davis had long-term mental health issues. Family members also told police that they were trying to contact Smith throughout the day, as she could typically calm Davis down. James Davis II, Davis’ father, eventually made arrangements to take his son to see his mother. Davis was in possession of multiple firearms According to Ross, investigators learned Davis was in possession of a .357 revolver and an AK-47 rifle when he went to his father’s house. Ross said Davis brought other firearms to the house, as authorities recovered them after the shooting. Ross also said Davis had the revolver and rifle with him when he went into his father’s vehicle to meet up with his mother, and he then brought those guns into his mother’s vehicle. When asked if there was any attempt by Davis’ family to remove the guns from his possession, Ross said he did not believe there was any discussion of removing the firearms or calling the police based on interviews conducted by investigators. Timeline of shooting Police said that shortly before 4:15 p.m., Smith was driving on King Road and approaching the intersection of Middle Road, which is part of Route 9, when Davis shot her with the .357 revolver. Ross said investigators believe Smith was likely driving her son home when he shot her. The vehicle then traveled across Middle Road before coming to a stop on someone’s front lawn, a property that is near the Lisbon town line. Davis then exited his mother’s vehicle armed with the AK-47 and began shooting at vehicles that were traveling on Route 9 from Lisbon into Sabattus. Three drivers were struck by the gunfire: 53-year-old Katherine Williams, of Sabattus; 19-year-old Tyson Turner, of Jay; and 35-year-old David Wilson, of Hartford. Shortly after firing into traffic, Davis turned the AK-47 on himself and died of a self-inflicted gunshot wound. Authorities said the incident played out over a matter of minutes. What happened to the victims Police said Smith, Davis’ mother, was pronounced dead at the scene. Ross said Williams’ vehicle crashed into a nearby home. She was transported to Central Maine Medical Center in Lewiston, where she was pronounced dead. Turner and Wilson, meanwhile, were among several people who called 911 to report the incident. Both men were transported to CMCC with non-life-threatening injuries and they have since been released from the hospital.  What we know about one of the victims Williams, who went by the nickname “Kay,” worked for Regional School Unit 4. She was the food service manager at the Carrie Ricker School and Libby Tozier School, which are both located in Litchfield. “There is no question that her death will have an impact on all of us, as Kay was a beloved member of the RSU 4 community,” Superintendent of Schools Katy Grondin wrote in a letter to families. “Our thoughts are with her family as they begin to process this loss.” Shooting was partly a random act of violence While Davis did shoot his mother, Ross said police did not believe he had any connection to the three drivers he shot at with the AK-47. “This is something that you don’t see very often, even though we saw it in Bowdoin not too long ago,” Ross said. “But it is uncommon.” A question that remains unanswered When asked if Davis had a history of drug use, Ross said that is something police are still investigating. An autopsy conducted by the Chief Medical Examiner’s Office in Augusta will determine whether Davis was on drugs at the time of the shooting. Ross said investigators did not find any drugs, and Davis’ family did not indicate he was on any.
