The search for a missing Indiana 14-year-old believed to be in "extreme danger" continues Monday.

Scottie Dean Morris, described as a 5-foot, 4-inch White male weighing around 150 pounds with brown hair and blue eyes, was last seen around 8:30 p.m. Thursday in Eaton, Indiana, which is 76 miles northeast of Indianapolis. "He is believed to be in extreme danger and may require medical assistance," the Indiana State Police wrote in issuing a Silver Alert on Friday. 

Eaton Indiana Police Department, which organized search parties Friday and Saturday, said a ground search would not be conducted Sunday because helicopters from the Indiana State Police would be using their infrared cameras in an attempt to locate Morris. 

"We ask that if you continue to search on your own today, please refrain from wooded areas, tree lines, rivers, etc. as this will only hinder the investigation while they’re in the air searching," the department said on Facebook. "Scottie, please know we really do want to find you safe and help you anyway we can! If you read this, please contact us!"
