Rich was murdered on July 10 when he was shot multiple times in the back outside of his D.C. home.

“The entire Rich family is so heartened by the outpouring of support and love that they have felt over the past few weeks as they continue to come to terms with this terrible tragedy. The family is in constant contact with authorities and thank them for their extremely thorough investigation. The family believes this matter is being handled professionally and with the seriousness that it requires,” a spokesman for the family said.

“The family welcomes any and all information that could lead to the identification of the individuals responsible, and certainly welcomes contributions that could lead to new avenues of investigation. That said, some are attempting to politicize this horrible tragedy, and in their attempts to do so, are actually causing more harm that good and impeding on the ability for law enforcement to properly do their job. For the sake of finding Seth’s killer, and for the sake of giving the family the space they need at this terrible time, they are asking for the public to refrain from pushing unproven and harmful theories about Seth’s murder.”

Anyone with information on Rich’s murder is asked to call police at 202-727-9099. Information can also be submitted by sending a text message to 50411.

This story was updated to include a statement from the Rich family.
