Police: Soldier Killed Rockville Girl and Himself in His Germantown Home

Missing Rockville High senior planned to enlist in Army Reserve, police said.

Update, 7:30 p.m.: 

A Rockville High School student was shot and killed by a 31-year-old Army staff sergeant, who then turned the gun on himself inside his Germantown home, Montgomery County police said in a news release.

Michelle Miller, 17, of the 5100 block of Russett Road in Rockville, was found dead Monday morning in the home of Adam Anthony Arndt, 31, of the 12900 block of Pinnacle Drive, police said.

Investigators are treating the deaths as a murder-suicide. 

Police said Miller and Arndt knew each other because she had plans to enlist in the U.S. Army Reserve after she graduated from high school.

The bodies were discovered around 10 a.m. by police who were following up on a tip that the Miller was at Arndt’s residence, police said. Police had to force their way inside after they were unable to make contact.

In a letter sent home to parents, Rockville High Principal Debra S. Munk described Miller as an active member of the senior class, an honors student and a member of the varsity lacrosse team. 

“For those of you who did not know Michelle, we ask that you respect our sadness and support us with your understanding,” Munk said in the letter.

Update, 4:44 p.m.: The body of a girl found in Germantown on Monday has been identified by WUSA9 as Michelle Miller, a 17-year-old Rockville High School student.

The report cites a letter that was sent to parents from the school: 

"Tomorrow, a support team of psychologists, counselors, and pupil personnel workers from Montgomery County Public Schools will work with our staff members to provide counseling and support to students."

On Monday, Montgomery County police discovered the bodies of a teenage girl and a 31-year-old man. Police said the teen had been reported missing and they were following up on a tip that she may have been at a home on Pinnacle Drive.

Officer Janelle Smith, a county police spokeswoman, told Patch was unable to confirm whether Miller was the the 17-year-old found at the home.

Original post, 3:59 p.m., April 8: The bodies of a teenage girl and a 31-year-old man were found inside a Germantown home Monday morning, county police said in a news release.

Police described the deaths as “suspicious.” Limited information was available as of Monday afternoon.

The bodies were discovered by police, who were following up on a tip that the girl—a 17-year-old who had been reported missing—was at a home in the 12900 block of Pinnacle Drive, where the 31-year-old man lived, police said.

Police forced their way inside around 10 a.m. after they were unable to make contact with anyone.

Officer Rebecca Innnocenti, a Montgomery County police spokeswoman, said she was unable to disclose how or where inside the home the bodies were discovered or how the man and the girl knew each other. The two were not strangers and police are not looking for suspects in the deaths, Innocenti said.

Police have not released the identities of the girl or the man, pending notification of family members.

We now know there was more to the story. The parents were aware that the girl knew this man on a personal level. Why was a 17 year old girl allowed to socialize with a 31 year old male? The parents allowed her to go out at 9:15 on a Sunday night to handle a suicide crisis--an admittedly adult situation. I'm not trying to blame the parents, as this is a very sad situation, but parents (in general), please understand that your children are still children, and need your guidance and help in making decisions. To go out at 9:15 on a Sunday night at all, let alone to help a suicidal person...the answer is "No".
