Detectives say it appears someone or several people vandalized the houses some time after midnight. Police are investigating the vandalism as a hate crime.
Authorities say concerned and shocked residents in the community awoke to the offensive, hate-laced words and called police.
"It makes me feel sad. It makes me feel sick to my stomach. This is not our neighborhood. We don't have this hate around. I've been here since 1989, and I don't even know if this is a white-power group. Maybe it's somebody trying to make it look like it is, and it's a racial war instead," said Palmdale resident Terri Muns.
"Things have been getting a little itchy ever since the economic depression. People have been claiming their territories a little bit more. Personally, this is terrible. This is horrible because it's like Terri said, we don't see color here. We all chill out front. We have Mexicans, we have blacks, you know everyone, white -- we all chill. We have a blast. We have fun together. This really puts my heart in a sad place," said Palmdale resident Kevin Brown.
"We're certainly investigating it as a hate crime. There's certainly some target-specific groups here," said L.A. County Sheriff's Deputy Dave Jennings.
Sheriff's detectives need the public's help finding suspects. If you have information regarding this case, please call the Palmdale Sheriff's station at (661) 272-2400.
