HENRICO COUNTY, Va. (WRIC) — A teenage boy charged with shooting and killing 13-year-old Lucia Bremer as she was walking home from school in Henrico County in 2021 pleaded guilty to first-degree murder Monday, Jan. 23.

Deciding to forgo his scheduled three-day jury trial, the now 16-year-old Dylan A. Williams was just 14 years old when he shot and killed Bremer as she was walking home from school with a friend in March 2021. According to 8News sources, Williams followed closely behind the two girls as they walked on a path in the Gayton Forest West subdivision. When he approached the young girls, Bremer’s friend pushed the gunman back and ran to a nearby house, yelling “gun! gun!” Williams then fatally shot Bremer nine times.

The source said Williams did not know Bremer or her friend.

Williams was tried as an adult on all charges and also pleaded guilty to the attempted murder of the friend walking with Bremer, and the use of a firearm in the commission of a felony.

Beginning in 2018, Williams was hospitalized two separate times for mental health issues after he was charged with assaulting his mother, a counselor, and two Henrico Police officers. He was never convicted, and the charges were dropped.

Williams has undergone multiple psych evaluations, one of which diagnosed him with “unspecified trauma or stressed related disorder” and “unspecified neurological developmental disorder.” In a previous court appearance, Williams’ defense argued for his rehabilitation in place of incarceration, saying he had a challenging home life that left him traumatized and unstable.

In a tragic start to life, Williams’ father was murdered when he was just two years old. Later down the road, his mother died from an asthma attack and heart attack just a couple of years before Williams decided to fatally shoot 13-year-old Bremer using his legal guardian’s gun.

It was also revealed in court that in the years preceding Bremer’s murder, Williams allegedly brought a knife to school and had been in trouble with the school for allegedly sexually harassing female classmates, including threatening to rape another student. A school resource officer testified in court to often being called to respond to incidents involving the troubled teen.

Less than two weeks before Williams shot and killed Bremer, Henrico Police said he used social media to threaten to perform a mass school shooting. He also allegedly tried to recruit other students into what he called a “Satan gang.”

In court Monday, Jan. 23, Williams pleaded guilty to charges of first-degree murder, second-degree murder and possession of a firearm in the commission of a felony. His sentencing hearing will take place on April 14 at 11 a.m.
