Sharon Carr

Lasting notoriety Carr's case has been noted for being particularly unusual. While female murderers are themselves uncommon, females who kill strangers are even more unusual, and the case of a 12-year-old girl killing an adult stranger has been described as unique. This led to renewed media interest in the school and the Carr case, with allegations being made that there was a culture of problems at Collingwood. Carr's case also returned to the news in 2016 when two female children were convicted of the murder of a vulnerable woman named Angela Wrightson, which led to comparisons with Carr's case.

Another known case of a child killing an adult stranger was the 2023 murder of 19-year-old Shawn Seesahai by two 12-year-old boys.

In popular culture Carr's case has featured in a number of documentaries: In 2014, Carr was the subject of a season 8 episode of Deadly Women, titled "Never Too Young". The show incorrectly states her sentence as life without parole. In 2017, Carr was the subject of an episode of Teens Who Kill, a series shown on Channel 5. In 2017, a documentary on Carr, made by television personality Jo Frost, aired on Crime+ Investigation, as part of the series Jo Frost on Britain's Killer Kids.
