Cullen said Friday that Jones had yet to be interviewed by police.

“The state police have the mayor’s offer to be interviewed and we are waiting to hear when they would like to schedule it,” he wrote in an email. “Typically in situations like this, I would expect his interview would take place at the later stages of their investigation.”

State police spokeswoman Corinne Geller declined to comment on the status of the investigation.

Jones was copied on church-related emails that Branch sent from her RAA account, as well as emails from Adediran’s city account updating church leaders on the progress of the construction, distributing related documents, and coordinating with Chesterfield’s planning and inspection departments.

Jones pledged to maintain a wall between his public life and private responsibilities when he took office in 2009; about 10 percent of the top jobs in Jones’ administration are filled by First Baptist parishioners, of which there are about 3,000, according to his press secretary, Tammy C. Hawley.

Hawley said city policy allows employees to engage in limited personal communication during work hours.
