GREELEY, Colo. (AP) -- More than 20 police officers and FBI agents were searching Wednesday for a 12-year-old Greeley girl missing since Sunday, when she left home to go to a friend's birthday party.
Kayleah Wilson was headed to meet a friend in an area just across a busy highway from her home, but never made it to her destination, police said. Greeley is about 60 miles north of Denver.
Police using dogs found nothing in a search along the highway, Greeley Police Sgt. Joe Tymkowych said. Investigators have also conducted interviews with friends, family and acquaintances and have found nothing to indicate that she ran away.
''We've gotten no reason, nothing that would indicate a conflict to cause her to run away,'' said Tymkowych, adding there also are no indications of conflicts involving drugs, alcohol or gangs.
Tymkowych said they have contacted the girl's father, who lives in California, and other family members to advise them that she's missing and may be contacting them if she ran away. Tymkowych says Wilson had a boyfriend, who has been interviewed and is cooperating. He is not considered a suspect or person of interest.
The middle school student is 5-foot-1, weighs 145 pounds and has brown hair and blue eyes. Authorities say Kayleah has asthma and was believed to be carrying an inhaler. She doesn't have a cell phone.
FBI Denver field office spokesman Dave Joly said the FBI regularly provides help in investigating possible child abductions.
