Two Prince William County teens who were found dead in a Triangle, Va. home on Monday died as the result of a suicide pact, the Post is reporting. Police say they may never know what prompted to Desiree Patrick, 17, and Quirinius Williams, 18, to kill themselves together, but these comments from Williams’ stepfather, Ruben Aguilar, are fairly haunting:

Aguilar said he had never met Patrick but had received a phone call from her father about a year ago about the relationship. After that conversation, Aguilar said, “we made sure to tell them to stay away from each other.” From all appearances, Williams complied.

“We had no idea he was seeing her,” Aguilar said.

The Patrick family also released a statement to the media, which reads, in part, “Perhaps our loss will serve as a reminder to all of us that outward appearances can be very different from what is going on inside the mind of someone you love.”

Just brutally sad.
