Blood pact between two island teen girls goes bad

Two teenage girls who tried to consecrate their newfound friendship by becoming "blood sisters" ended up in the emergency room when, in their drunken state, they miscalculated how deeply to cut themselves, according to a Beaufort County Sheriff's report released Wednesday.

The two girls -- ages 16 and 17 -- were seen covered in blood running along Squires Gate Road on Hilton Head Island at around 3:30 p.m. Dec. 20.

One of the girls told a deputy that the two had recently become "best friends" and they tried to commemorate their relationship by mixing their blood, the report said. They also had been drinking all day, the report said.

Inside a home on Monticello Drive, they took a knife and cut their hands. One of the girls cut herself too deeply, causing the wound to bleed profusely, the report said.

The pair panicked and ran outside, calling 911 in the process. They were taken by ambulance to Hilton Head Regional Medical Center, where their parents joined them. The teens were treated and released.
