Imperial, MO (KSDK) - There is an update in the case of a sudden student death.
We should know Friday what killed a popular high school freshman.
Jacob Siebert died earlier this week. He was a football player at Seckman High School.
The superintendent says Siebert was not at practice or a game when he collapsed. He did attend practice last week, but had not told his coaches or trainer about any injuries.
The medical examiner's office says autopsy results should be back Friday.
