In the spring of 2021, Cecilia Williams lost her son, daughter-in-law and grandson to a drunken driver.
Williams, who lives in Bonne Terre, is now raising the two orphaned grandchildren who survived, Bentley and Mason.
A year later, Melanie Wankum was hit head-on by a drunken driver, killing her instantly and injuring a passenger on their way back from a wedding.
In both tragedies, families of the victims became advocates on their behalf, championing tougher laws in Missouri against drunken driving.
Soon after the crash that killed her son and his family, Williams found herself in Jefferson City lobbying for a bill that would hold drunken drivers responsible for children left without a parent after an accident.
It would require convicted drunken drivers to pay child support to the surviving children until they are at least 18, or 21 if they are still in school.
Named after Williams’ grandsons, the legislation was introduced in 2021 and signed by the governor five years later on July 9. Tennessee was the first state and Missouri was the eighth to pass a version of “Bentley Law.”
The child-support provision was included this year in Missouri House Bill 1740, which also stiffened other drunken driving laws. The additional provisions have become known as “Melanie’s Law,” to recognize the woman killed in 2022 by a drunken driver in Jefferson City.
Melanie’s Law changed felony classifications for DWI cases that cause injury or death to require longer prison sentences. It also expanded the mandatory use of ignition interlock devices for those involved in alcohol-related incidents. Missouri is one of 35 states with similar laws.
“The pain a family feels when a loved one is killed by a drunk driver is one that never goes away,” said state Rep. Dave Griffith, who sponsored the legislation.
The bill went through a number of revisions before it was passed, Griffith said.
“At each one of those steps, I think we’re very thoughtful about how we can make the bill better and how it’s going to affect the families that suffer and deal with this,” Griffith said.
“Driving while intoxicated is a choice,” he said. “It’s my hope that when people know the ramifications of making those bad decisions they will think twice before getting behind the wheel.”
Mothers Against Drunk Driving, a national organization with offices in Missouri, has been consistently involved in pushing for enactment of the stricter legislation. Working closely with Cecilia Williams, the organization supported the Missouri bill until it passed.
“Cecilia has been dedicated to turning the tragic crash into a way to honor her loved ones, as well as raise awareness of the dangers of driving impaired,” said Tabitha Perkins, state executive director for Mothers Against Drunk Driving.
“For Missouri, we hope this bill will serve as a deterrent to individuals who drink and drive,” Perkins said. “Knowing that even after they are released from prison, they will still have a financial obligation to complete will make drivers think twice before they get behind the wheel of a deadly weapon in an impaired state.”
