Roswell police say specific threats were made against players on a high school lacrosse team.

Someone sent emails saying he or she would kill family members of Centennial lacrosse players, Channel 2 Action News reported.

Roswell police spokeswoman Officer Lisa Holland told Channel 2 the sender might have been joking, but police take it seriously.

“There were graphic details of what this person would like to do to each of these children on the lacrosse team,” Holland said.

Student Chris Ellingsworth told the television station that no one should make threats like these and “no one should have to deal with that, either.”

Specific people were mentioned and parents brought the emails to police, Holland said. But it isn’t easy to find the source, who would face a felony charge of making terroristic threats.

“The problem is there are so many programs out there that can mask people’s identity,” Holland told Channel 2.
