Nikki Miller, 16, may have run away, the Orange County Sheriff’s Department said. Deputies searched for her for hours, and authorities in neighboring cities were alerted.
Retired NBA player Reggie Miller asked his thousands of Twitter followers Monday to look out for his missing 16-year-old niece.
Nikki Miller disappeared from her Yorba Linda, California, bedroom sometime between 10:30 p.m. and 7 a.m. Sunday night to Monday morning, her parents told the Orange County Sheriff's Department.
"We are treating this as a runaway-type situation," Lt. John Roche told BuzzFeed News Monday evening.
When her family discovered she wasn't in her room Monday morning deputies arrived to investigate. Her room had been arranged to make it seem like she was still asleep, Roche said, and there was no sign of a struggle or forced entry.
But there also wasn't any sign of why she might have left. She had no history of running away, and there had been no argument or turmoil within the family, Roche said.
"We don't know why this occurred," he said.
Deputies searched the area for several hours, and bloodhounds were called in to look for any trace of her. Authorities in neighboring cities were also alerted, and her name and description were entered into a missing persons database.
