Is [3] Bill Priestap next in the line of fire?

The wiki on him is oddly lean.

Priestap is married to Sabina Menschel, the current head of the Washington, D.C., office of Nardello & Co, a detective agency.[6] Menschel's father, Richard Menschel, is a Goldman Sachs investment banker, philanthropist and Democratic donor, as is her uncle Robert Menschel.[6] His mother-in-law, Ronay A. Menschel, was a Democratic deputy mayor of New York City under Ed Koch.

Was it misdirection that he was a cooperating witness?
