Ohio State coach Urban Meyer’s suspension is over. Reporting on Meyer and OSU’s handling of domestic abuse allegations against former assistant coach Zach Smith, however, appears to be far from over.

The Wall Street Journal reported Wednesday that investigators made no effort to recover any deleted texts by Meyer or OSU AD Gene Smith. Whether Meyer deleted text messages is one of the many questions surrounding the investigation that has yet to be resolved.

According to the report made public by the investigators, Meyer asked a staffer how to delete text messages from his phone. When investigators obtained Meyer’s phone, they found no messages older than one year. At his press conference this week, Meyer strongly denied deleting text messages.

In the WSJ report, it is revealed that AD Smith’s phone had zero text messages. Smith said that he routinely deletes text messages. The WSJ article notes that Smith’s deletion of text messages could be a violation of Ohio open records law and OSU policy.

Despite the fact that Smith admitted to deleting messages and older messages were curiously absent from Meyer’s phone, investigators did not send the phones to a forensic lab to search for any deleted messages.

The probe was led by Mary Jo White, former chair of the Securities and Exchange Commission and current partner at law firm Debevoise & Plimpton LLP. When asked why the investigative team did not further investigate deleted text messages, a spokeswoman at Debevoise & Plimpton LLP issued the following statement to the Journal:

The Debevoise spokesman said investigators “determined they already had strong, indisputable evidence” on the core issue they were asked to probe—whether Mr. Meyer and Gene Smith knew of a 2015 police investigation into domestic violence allegations against Zach Smith.

At the conclusion of the investigation, Meyer and Smith were both suspended. Meyer is back as the team’s full-time head coach and returning to the sideline Saturday after being suspended from coaching the Buckeyes’ first three games.
