Girl, 13, and 18-year-old man sought in string of thefts in Western Ky.

Authorities in Western Kentucky are urging the public to be on the lookout for a man and a teenage girl who are suspects in a number of crimes.

Cheyenne Phillips, 13, was reported missing from her Grayson County home on Jan. 3, and is thought to be in the company of Dalton Hayes, 18, according to the Grayson County Sheriff's Department.

Hayes is wanted for custodial interference and other offenses, and both are suspected in at least two felony thefts and other crimes, Grayson County Sheriff Norman Chaffins said in a news release.

The two were thought to be driving a red 2006 Toyota Tacoma extended-cab pickup, but they might have stolen another vehicle, officials said.

"It is imperative that these two be located and apprehended, as their behavior is becoming increasingly brazen and dangerous," Chaffins said in a statement.

Anyone who sees the pair is asked to call 911 immediately with their location and any other information they can provide, the sheriff's department said.
