AURORA, Colo. -- Detectives continue to investigate a rash of bias-motivated crimes at an Aurora apartment complex over the weekend.
Vandals have spray-painted racial slurs and left threatening messages on the doors of complexes at the Sonoma Resort at Saddle Rock apartments in the 6700 block of South Rivera Court three times since November.
Five doors have been tagged and the Aurora Police Department said black residents and interracial couples have been targeted.
The doors were tagged with "KKK" and the N-word, and the perpetrators also left notes that read "Watch Ya Back Ya Stupid (N-word), - KKK."
Maintenance crews have since painted the doors white, but the community and police say the hate has to stop.
Since last year, police say Aurora has seen about one or two hate crimes a month. But since the election, police have investigated at least nine.
Police are calling the latest tag over the weekend a high priority and patrols have been added.
A $2,000 reward is being offered to anyone who has information that leads to an arrest.
Anyone with information is asked to call police at 303-627-3156 or Metro Denver Crime Stoppers at 720-913-7867.
Detectives say they believe there are many more of these types of crimes but they haven't been reported.
