NFL investigators concluded Tuesday that there is insufficient evidence to support a determination that Miami Dolphins wide receiver Jarvis Landry violated the league's personal conduct policy, a source told ESPN's Josina Anderson.

The NFL told Landry that its investigation is closed and it will not take action against him for alleged domestic violence reported to police on April 1. Prosecutors declined to pursue charges last month.

An investigation by the Broward County (Florida) State Attorney's Office determined there was "no reasonable likelihood" of a conviction for the incident that involved Landry and Estrella Cerqueira, who is the mother of the couple's daughter.

"The victim maintains that the defendant did not intent to touch her [or] strike her, but accidentally did so," assistant state attorney Stefanie Newman said in a memorandum.

There were no witnesses to the encounter, and Newman said that video surveillance appeared to corroborate Cerqueira's account.

Cerqueira had released a statement in early August via a publicist to NFL Network saying that she had a vocal disagreement with Landry in March and that police were called, although she did not call them.

Cerqueira also said in the statement that "there were no criminal charges" and that she "was not in any way physically harmed."

When the decision not to pursue charges was announced last month, Landry said in a statement that "my daughter's mother and I will continue to co-parent to raise our child in a happy and healthy environment. I would like to thank my family and friends for their continued support throughout this process."
