Authorities said they are investigating the apparent drug-overdose death of a woman who was dropped off at a Virginia emergency room Thursday by two men, one of whom was identified by people familiar with the matter as Washington Redskins safety Montae Nicholson.

The Loudoun County Sheriff’s Office said that 21-year-old Julia E. Crabbe of Reston was “unconscious and unresponsive” when two men drove her to the Inova Emergency Room-Ashburn HealthPlex about 1:30 a.m. Thursday. The health center is about four miles from the Redskins’ practice facility in Ashburn, Va.

People familiar with the situation, speaking on the condition of anonymity because of the ongoing investigation, identified one of the two men as Nicholson. The 23-year-old defensive back said through his attorney Thursday that he had no comment.

One person familiar with the situation said Nicholson and the woman were among a group that went out to dinner and then went to his Loudoun County home. The person said the woman was later found unresponsive in a bathroom and that Nicholson and the other man sought to get her medical care and waited at the emergency room until her family arrived.

“The female victim was pronounced [dead] at the emergency room,” the sheriff’s office said in a statement. “The two males who brought her to the emergency room immediately left the area but have since been identified and located.”

The case “is an active investigation being conducted by the Loudoun County Sheriff’s Office Criminal Investigations Division,” the statement said.

“We’ve been made aware of the tragic event and extend our deepest sympathies to the family who lost a loved one,” the Redskins said in a statement. “Our team has alerted the league office and is cooperating with local authorities. We fully support law enforcement and respect their process as they investigate the matter.”

Nicholson, a fourth-round draft pick from Michigan State University selected by the Redskins in 2017, recorded 35 tackles and two interceptions in seven games as a starting safety this season before missing the last two games with an ankle injury.
