KAYSVILLE -- Centennial Junior High School students are mourning the death of eighth-grader Rebecca Tibbitts.
The girl died unexpectedly Monday.
As of Thursday, police were still trying to determine the cause of death, Kaysville Police Sgt. Paul Thompson said.
It is police protocol to investigate the death of anyone who is not under a physician's care, Thompson said. He called the girl's death unusual, based on her age.
"As far as we can tell there is nothing suspicious (about the death)" and the continued investigation is centered on the cause of death. He said no foul play is suspected.
Police and emergency personnel responded to Tibbitts home just after 6 a.m. Monday, Thompson said.
A school assembly, scheduled for today, has been adjusted so students who want to attend Rebecca's funeral can do so, said Christopher Williams, Davis School District's spokesman.
Parents who want to take their children to Rebecca's funeral are reminded to check out their students at the office before taking them from the school, Williams said.
The funeral will be at 11 a.m. at the Kaysville West LDS Stake Center, 270 W. Burton Lane.
When word of Rebecca's death hit the school on Monday, about 30 students checked out early, Williams said. On Tuesday, many students wore their best dress, boys in shirts and ties and girls in dresses, to honor 13-year-old Rebecca, who was a member of the school's track team and Science Olympiad.
"When her parents visited the school on Tuesday, they were overcome with what they saw, the support from students and how great (Rebecca's) impact on her fellow students was," Williams said.
The school has three full-time counselors and two assistant principals who are trained in grief counseling and are available to any student who needs help, Williams said.
Rebecca is survived by her parents, Gregory Scott and Meganne Evans Tibbitts, five siblings, grandparents and extended family.
