The police have arrested a man accused of murdering his wife sometime after they attended their unit's Marine Corps Birthday Ball in Virginia last Friday, Task & Purpose has learned.

Arlington County police officers found Marine Lance Cpl. Natasha Rivera, 20, dead inside a hotel room in Crystal City on Saturday at about 9:40 a.m. Her husband, Cpl. Rodolfo Rivera, 24, was arrested at the scene and has been charged with murder.

The arrest was announced as a "domestic-related homicide," according to a police statement. Rivera is being held without bond in the Arlington County Detention Facility, the police said.

Both Marines lived in Stafford, Virginia, and were assigned to Headquarters and Service Battalion in the legal-services support section at Marine Corps Base Quantico as legal-services specialists. They attended their base's birthday ball together last Friday evening at the Crystal Gateway Marriott hotel, a source familiar with the matter told Task & Purpose.

The victim, whose maiden name is Soto, had just given birth to a boy in September and was still on maternity leave, according to the source.

"We are shocked and saddened by this tragic loss," Maj. Ken Kunze, an MCB Quantico spokesman, told Task & Purpose in a written statement. "Our deepest sympathies are extended to the Marines and families involved."

Kunze added that base officials were notified of the death and arrest on Saturday and were cooperating fully with the investigation, which is being carried out by the Arlington Police Department and the Naval Criminal Investigative Service.

According to Marine Corps records, Quantico was both Marines' first duty station and neither had ever deployed. Their only awards were the National Defense Service Medal and the Global War on Terrorism Service Medal.

Rodolfo enlisted from Cook County in Illinois on March 14, 2016; Natasha enlisted from Brooklyn, New York, on April 17, 2017.

A friend of Natasha's who went to boot camp with her has started a GoFundMe campaign for her family to pay for expenses and to help raise her infant son. "She had such a great presence," Olivia Golden wrote. "Anything you can offer will help immensely."
