ROCKVILLE, Md. (FOX 5 DC) - A jury has convicted a Maryland man for a 2010 rape inside a Gaithersburg nursing home.
The case came together after the suspect's DNA matched evidence left at the scene.
On Dec. 6, 2010, prosecutors say Davon Gray followed an 18-year-old into Asbury Nursing Home.
When she walked into a restroom, he followed her in and pulled out a gun - pointing it at her head and demanding all of her possessions, including $50 in cash.
Prosecutors say Gray then order the young employee to remove her clothes and then he raped her.
They say very next day, Gray was arrested in Montgomery County and charged with possessing a stolen firearm, but they did not have the evidence at the time to charge him with the rape.
It wasn't until May 1 last year that the crime lab was notified that a cold hit on Gray's DNA had been made with the evidence found at the 2010 scene.
Montgomery County State's Attorney spokesman Ramon Korionoff issued the following statement:
Virginia had gained a conviction against Mr. Gray on a drug intent to distribute case and so he was entered into the criminal database as part of their normal procedures and protocols and that then rendered a hit on our open rape query--there was a standing order with the various databases across the country and this particular one rendered the hit.
The trial lasted four days.
Gray was convicted of first-degree rape, armed robbery, and a weapons charge.
