The beating started over a missing $20 bill.

Now one young man is dead because of severe head injuries he suffered in a Clermont driveway. Another man faces a murder charge.

Clermont police say Brian Underwood was dropped off at the South Lake Hospital emergency room May 14 with a severe skull fracture and face laceration. His head injuries were considered life-threatening, so he was flown to Orlando Regional Medical Center. That's where he died this week.

Police pieced together a case and a series of events leading up to the 26-year-old's death. They found out that Underwood was at a party with some others on Shady Nook Lane in Clermont. That's where he became entangled in an argument with Clinton Scarbary, 23, of Clermont over some missing money.

Scarbary said Underwood had stolen $20 from him and demanded the money back, according to a police report. Scarbary admitted hitting Underwood once in the face and "breaking his nose." He also told authorities Underwood hit the back of his head on concrete when he hit the ground.

Scarbary told investigators Underwood denied taking the money and approached him with his fists up. Then, he said, he punched Underwood once "in the nose causing him to fall back, hitting his head on the concrete driveway," according to the report.

No care for hours?

Based on Underwood's injuries and the lack of witnesses, Scarbary was at first charged with aggravated battery. Doctors had given Underwood a 20 percent chance of survival. After Underwood's death Tuesday and follow-up interviews with witnesses, Scarbary's charges were upgraded to second-degree murder and unlawful imprisonment, police said.

Clermont police stated in a report that Underwood was deprived medical care for four hours after getting hit and striking his head on the concrete.

Witnesses said they saw Scarbary "punch Underwood repeatedly in the head and face even after he was unconscious laying on the ground, unable to defend himself," according to the arrest affidavit.

The witnesses also told investigators that Underwood was brought to a bedroom inside the Shady Nook Lane home and left there. They said Scarbary "refused to allow Underwood to leave the residence after the attack," according to the report.

The witnesses specifically said that Scarbary "threatened bodily harm to anyone that assisted in removing the victim from the home," the report states. Several thought the victim's injuries were serious enough for immediate medical assistance.

'Seen convulsing'

Several also heard Scarbary say Underwood was not leaving until he collected his money. Underwood was kept there for several hours, they said, before he was dropped off at the hospital. These witnesses also saw Scarbary going through Underwood's pockets after the attack. He removed his wallet and a cell phone, they said.

Police later confirmed that a Roderick Doyle had dropped off Underwood at the hospital. Initially, Doyle told them that he and his girlfriend found Underwood along the side of the road and took him to the emergency room.

But Doyle later recanted that story and said Scarbary had called him about the fight. Doyle told police Scarbary has "anger management problems," according to the report.

Doyle's girlfriend, Brittney Adams, said she and Doyle went to the home and saw Underwood unconscious. "She stated that at times the victim was seen convulsing," the report states.

South Lake Hospital physicians said Underwood suffered an occipital skull fracture, a nasal bone fracture, brain hemorrhaging and brain swelling. After he arrived at ORMC, doctors there placed him on life support and said that because of his severe injuries "his body was unable to sustain life without external assistance."

He was removed from life support at about 4:50 a.m. Tuesday and pronounced dead at the hospital
