Research has shown that a significant proportion of young people in custody have experienced some form of abuse and/or loss in their lives. This article uses the biographies of three young men (all serving custodial sentences) to elucidate the feelings that experiences of this nature can engender. Crucially, none of the three was effectively helped to resolve their experiences. The article goes on to argue that more needs to be done to identify and support traumatised young people in custody. The article concludes that, while the CHAT: Secure tool may go some way to better identifying those needing support, an individual's reluctance to disclose their traumatic experiences in the first place may limit the tool's efficacy.Research has shown that a significant proportion of young people serving custodial sentences in England and Wales have lived through traumatic experiences and events (see Arnull et al. 2005;Boswell 1991Boswell , 1996Jacobson et al. 2010). For example, in their study of 200 young people in custody, Jacobson et al. (2010) found that around two-fifths had been on the child protection register and/or had experienced abuse or neglect. Furthermore: 14% had a parent with physical or mental health problems or learning disability; 12% had a mother/step-mother who had misused drugs or alcohol; 7% had a father/step-father who had misused drugs or alcohol; and 6% had experienced the death of a father, 4% a sibling, and 3% a mother. Additionally, just over a quarter had been in local authority care for one or more periods of time. Indeed, many of those who had been in care had been subject to multiple placements in different kinds of care over several years. Bearing in mind that these figures are based on officially recorded data, as Jacobson et al. point out, they are likely to be significant underestimates.If the focus shifts to those young people serving custodial sentences for more serious offences, then the prevalence of traumatic experiences 434 C 2015 The
