CONCORD, N.H. (WHDH) -- Police in Concord, N.H., are investigating hate-filled graffiti left on the home of Somali family, similar to graffiti left on three other homes last September.

“I don’t know why they do this to me,” said the woman who lives in the house.

The family woke up and discovered the racist message on Sunday. Like the ones left on the homes last year, it was written in permanent marker.

It says, “We cannot coexist with third-world scum,” and those that live in the home are, “primitive beasts,” who are to blame for crimes, “we now suffer.” The message was signed, “Love, your legals, deport the rest.”

“My neighborhood is very good. Everybody’s nice -- never see problem,” said the man who lives in the house.

The couple says they are proud to be Somali and they are living and working in the United States -- with their children -- legally.

“We don’t believe it’s a coincidence given what happened the previous year, further south of that location we became immediately concerned that this was similar” said Lt. Timothy O’Malley, Concord, NH Police Department.

Authorities say three families were victims of the same kind of crime.

“They’re very nice people, they haven’t given any issues, they fit right into the neighborhood, they’re growing a vegetable garden out front,” said Jean Tewksbury, works next door.

“I’ve travelled to Africa, I’ve studied abroad there. It’s very sensitive to me and it’s disturbing,” said Lindsey Herbert, a family friend.

Police are asking for the public's assistance in solving the current case.
