CONCORD, N.H. — Most victims killed by domestic violence in New Hampshire did not seek help, even though more than half of the perpetrators had a history of domestic violence.

New Hampshire Attorney General Michael Delaney said Monday that of the 79 domestic violence-related homicide victims during the decade ending in 2010, only 6 percent had sought crisis center services and only two victims had a protective order in place when they died. He noted that 53 percent of the killers had a known history of domestic violence.
