Moeller was suspended indefinitely by the Browns earlier this month.
Prosecutor Jim Walters issued a statement regarding the decision not to press charges.
“It is quite clear that an incident of a volatile nature took place between Mr. Moeller and [the accuser] on the evening of the call but what is less clear is the exact nature of the incident and the actions of the two persons involved,” Walters said.
A woman claiming to be Moeller's fiancée called 911 on Sept. 6 and said he tried to strangle her. She went on to file a complaint against Moeller but said she did not want to pursue charges. Investigators handed over the case to Walters for review.
Moeller joined the Browns as offensive line coach last year. From 2008–13, Moeller worked with the Baltimore Ravens’ offensive linemen.
The NFL suspended Moeller for two games in September 2011 for violating the league's personal conduct policy. The suspension stemmed from a Moeller being found guilty of driving while impaired by alcohol. In a four-year stretch through 2011, Moeller had three alcohol-related arrests.
The Browns will host the Oakland Raiders on Sunday. Cleveland is off to a 1–1 start to the season after dropping their season opener to the Jets but rebounding with a 28–14 victory over the Tennessee Titans in Week 2.
