Pippen’s agent, Kyle Rote, did not immediately respond to CNN’s request for comment.

Detectives want to ask witnesses additional questions before concluding their investigation, the sheriff’s department said in a statement.

Pippen was a longtime player for the Chicago Bulls. He was inducted into the Basketball Hall of Fame in 2010.
