From September 2010 to May 2013, Crutchfield was an assistant men’s volleyball coach at Long Beach City College, said John Pope, director of communications for the school.
Crutchfield was also an assistant coach with the SCA Girls Volleyball Club in Huntington Beach when he was arrested, said club director Kim Lucero.
The Orange County Child Exploitation Task Force was contacted about the inappropriate conversations and began an investigation.
Detectives do not believe he had inappropriate relationships with members of the team, Stichter said.
It was not immediately clear if Crutchfield ever met the girl in person or how many videos were sent, Stichter said.
Orange County sheriff’s officials took Troy Linehan Crutchfield, 26, of Costa Mesa, into custody at his home Wednesday morning after serving a search warrant, said Lt. Mark Stichter.
