Prince William County police said have arrested a 17-year-old in the double slayings of a Dale City woman and her teenage son.

Commonwealth’s Attorney Paul Ebert said Monday that Jean C. Smith, 39, and her son James Smith, 19, were killed during an attempted burglary at their home on Langford Court on Friday afternoon.

The 17-year-old, who lives in the neighborhood, has been charged with two counts of first-degree murder. The teen’s girlfriend, 22-year-old Jacqueline Munoz, has been charged with obstruction of justice for allegedly providing him an alibi, police said.

Ebert said he is seeking to have the murder charges upgraded to capital murder. But he is unable to seek the death penalty due to a Supreme Court ruling banning capital punishment for juveniles.

Police provided a chilling account of what happened in the Smith home on Friday afternoon.

I was a neighbor of the Smith’s they are wonderful people. I feel privileged to have know her. As for this 17 year old I don’t know who he is yet, but he should get the death penaty.If he gets life lets all pray that he has a 350 lb. cell mate named Bubba that hasen’t been laid in 10 years.

I haven know the Smith’s for years, and this is a sad thing.  My heart goes out to Rick, the kids and the rest of the family.

I think this kid should be charged as an adult.  Whatever he got was it worth taking two lives for?
