What we know about suspect Robert Card

A manhunt is now into its second day for Robert Card, the suspect in a mass shooting in Maine that killed at least 18 people and wounded 13 others, officials said.

The suspected gunman — identified as 40-year-old Robert Card — is a U.S. Army reservist, the Army confirmed.

Card’s family is cooperating with authorities, law enforcement officials briefed on the investigation told ABC News. Card’s sister told investigators she thought Card might have been looking for an ex-girlfriend at the shooting locations, the sources said. One avenue of investigation is whether this mass shooting began as a domestic dispute, according to the sources.
Card was previously married. His ex-wife filed for the divorce, citing irreconcilable differences, which was granted in 2007 with shared custody of the couple’s minor child, court documents show. The divorce order was amended in 2013 to include shared parental rights and responsibilities of the child, whose primary residence was with his mother, the documents show.
