Florida man accused of shooting, killing ex-wife, her son over argument about electricity

VOLUSIA COUNTY, Fla. - A mother and her adult son were shot and killed over an argument with a suspect about electricity Sunday night, the Volusia Sheriff's Office told reporters Monday during a news conference.

Shortly before 8 p.m., authorities said the suspect, identified as Michael Williams, 47, called 911 reporting he had shot two people. When deputies arrived to the home on East Parkway in DeLand, they found Marsha Williams, 48, and her 28-year-old son Robert Adams dead inside.  

"Michael gave us a story that he was attacked by Marsha and Robert and this stemmed from an argument that occurred over the past couple days about the electricity in the house," a spokesperson for the sheriff's office said.

The suspect was allegedly upset that he felt they were leaving the lights on the house. He reportedly put a lock on the electricity box outside the house, to which the mother and son cut. 

Robert Adams' two children – ages 5 and 6 – were home at the time of the shooting and may have witnessed the murders, the sheriff's office said.

Officers are working with the Department of Children and Families to interview the children.
