The deputy ordered the female to stand, turn around and put her hands behind her back.
Deputies took over doing the CPR until paramedics arrived and took Hoover to the hospital.
Monday afternoon, the coroner's office ruled the incident a homicide and said Hoover died of multiple stab wounds.
Detectives interviewed two brothers at the scene and took a 22-year-old woman in for questioning, according to the incident report, which indicates that the 22-year-old is dating one of the brothers and that Hoover is that same man's former girlfriend.
Hoover apparently lives next door to her former beau and why she was at his house early Sunday has not been made clear so far in the investigation, according to detectives.
