Bone's body was found by a paddleboarder just before noon on Friday in the lake north of downtown Orlando.  It was located underneath the Interstate 4 eastbound bridge, authorities said.   

Friends of Bone had been frantically looking for him after he disappeared during a pub crawl on Sunday. The group said Brian’s last known location was Swigs at 50 E. Central Blvd., and they think he left at around 7:30 that night. 

Brian's roommate, Bryan Caballero, said that Brian seems a bit ‘abnormal’ that night.

"A little bit more than just intoxicated," explained Caballero. 

His mother, Inez Favors, said she Facetimed Brian on Sunday evening for about 10 minutes. She was worried because family members told her he sounded drunk and was slurring his words. 

Friends later told FOX 35 News that Brian’s phone was turned off and his car was still sitting in the garage where he had parked on Sunday.

"We lately can’t sleep, cannot eat, thinking about our son," Nixon Bone said. 

At 11:55 a.m. on Friday, Bone's body was pulled from Lake Ivanhoe. A medical examiner will determine his cause of death. 

Anyone with information is asked to contact police.
