COLLIER COUNTY, Fla. - Family and friends remembered a 20-year-old Naples man who died suddenly last week. 
Doug Miller was a Junior at Florida State.  He graduated from Gulf Coast High School in 2008.
"A couple of days before it happened we were leaving for thanksgiving and the last thing you say is I'll see you when we get back," said Miller's roommate Eric Witkowski.
But, Miller's friends never saw him again.  Witkowski says Miller suddenly felt sick right before Thanksgiving. 
"Thought it was the common cold, his mom took him to the doctor and he passed away," said Witkowski.
Friends say Miller had bacterial meningitis.  it's a serious infection that affects the brain and spinal cord.  The World Health Organization says it can cause severe brain damage and is fatal in 50% of the cases if left untreated. The Collier County Health Department has still not received Miller's tests back, and can't confirm yet if that's what killed him.  Friends say anyone who came in close contact with him has been checked out and they're all fine.
"As roommates we had to go to the hospital," said Witkowski. On Friday, hundreds of people packed St. Agnes Catholic Church to remember the bright young man and high school football player.  Now, friends say their lives will never be the same. 
"Its going to be so weird to go home and not have him with us," said Miller's friend Rebecca Sierra. 
"Truly God got one of his angels back," said Witkowski.
Memorial gifts can be made in Miller's name to the Florida State University Foundation.
