Megan Boken, 23, was killed Saturday afternoon while sitting in her car in the Central West End neighborhood of St. Louis.

One of Boken’s close friends was her former college roommate and volleyball teammate Bridget Fonke.

“I really want to make this funeral and this ceremony a big celebration, like a big party, because that’s what she would have wanted,” Fonke said.

Fonke now plays volleyball in Europe. She is back home for the funeral.

She says Boken “loved people, and loved to have a good time. She never even whined, never whined or complained about anything. She was always focused on the positive, and I just want this to be a celebration of her life.”

She says it is “frustrating and scary” that the killer is still out there.

A 2011 Saint Louis University graduate, Boken was in St. Louis for a reunion game for former volleyball players, scheduled to take place about two hours after she was killed. When she didn’t show up, her teammates knew something was wrong.

Authorities initially said there were conflicting reports about the gunman, and that it was possible Boken knew her attacker. But, on Monday, St. Louis Police spokesman David Marzullo said there was no evidence she knew the gunman, and detectives were investigating the case as a probable attempted robbery.

The gunman has been described as a black male, with a medium complexion, and a thin build. He is 5’8″ to 5’10”, with short hair, and was last seen wearing a grey charcoal shirt, khaki pants, and white tennis shoes.

Boken’s teammate Sarah Entzeroth said earlier this week, “There is no way she knew this person. No way. Not possible. We don’t hang out with people that have guns, or that carry guns, or that hurt people. No one that knew Megan Boken would ever hurt her.”

Boken had been planning to move back to St. Louis from the Chicago area, where she and Entzeroth were planning to be roommates.

The reward now stands at $20,000 for information leading to the arrest of Boken’s killer. The Central West End Neighborhood Security Initiative put up $10,000, and an anonymous donor has matched the amount.
