BOYFRIEND CHARGED:

Marco Holmes, the boyfriend of 20-year-old Tonja Chadwick, has been charged with murder in her death.

Baltimore police announced murder charges Thursday against the boyfriend of 20-year-old Tonja Chadwick and said the woman’s killing came after incidents of domestic abuse.

Marco Holmes, 22, is charged with firstand second-degree murder, first-degree assault, and gun charges.

Police said Chadwick suffered a gunshot wound to her head. Her body was found wrapped in bedding, underneath debris in a wooded Southwest Baltimore area known as Daisy Park.

Police spokesman T.J. Smith said detectives learned from family and friends that there was a history of “undocumented domestic incidents” between the two.

“This apparently is the culmination of it,” he said.

Holmes was taken into custody at a home in Northeast Baltimore on Wednesday on an unrelated violation-of-probation warrant.

He was being held Thursday without bond and did not have an attorney listed in court records.

Chadwick was an aspiring nurse and the mother of a 4-year-old boy. She was last seen Jan. 28 leaving her aunt’s home in Belair-Edison. Days later, her body was found in the park.

Investigators said they believe Chadwick was killed in her apartment, not far from her aunt’s home.

They allege Holmes killed Chadwick after an argument.

After Chadwick went missing, police found bloodstains in the apartment and evidence that someone had tried to clean up the blood.

Initially, “we didn’t put that information out specifically, but that is what took this to critical missing-person level,” Smith said.

He declined to elaborate on any statements Holmes might have made to detectives.

He said police located Holmes’ vehicle and that there was evidence that the trunk area “had been cleaned out.”

Smith thanked the public for tips that poured in after Chadwick’s disappearance, including information about where to look for her body.

“That allowed us to get a quick case closure in this scenario,” he said.

Chadwick’s family members have said the young woman was a devoted mother, and they knew something was wrong when she didn’t respond to calls and texts.

She completed a program this past summer to become a geriatric nursing assistant and wanted to go to nursing school, her family has said.
