More than 125 people have signed up to attend, and Joel said it goes “until people run out of stories to tell about Seth.”

Three and a half weeks ago, Seth Rich was fatally shot after 4 a.m. while walking home in his northwest Washington neighborhood. His father said Seth had been on the phone with his girlfriend just before he was attacked.

D.C. police have announced no arrests or even leads in Rich’s killing.

“The case remains under investigation,” police spokeswoman Aquita Brown told The World-Herald on Tuesday. “There are no updates.”

The Riches plan to meet this morning with detectives and the Washington police chief. Joel said he “absolutely” believes that it was a random crime.

He said the police “have been extremely helpful and caring about the family.”

Though he and his family will always grieve Seth’s early death, Joel said, the outpouring of sympathy from all parts of their son’s life has helped.

The Riches learned last Friday afternoon from the Clinton campaign in Omaha that the presidential candidate wanted to meet them. Monday morning, the couple were told that photos would be taken.
