Indiana State Police detectives investigating the murders of Libby German and Abby Williams said Monday they want to speak to anyone who may have had an interaction with the social media account "anthony_shots." 

The suspect is believed to be between 18 and 40 years old, although he may appear younger.

Kelsi German's 14-year-old sister Libby was killed, along with 13-year-old Abby Williams, in February 2017 while hiking in Delphi, Ind.

The Carroll County Sheriff's Office says there is a right way and a wrong way to alert authorities of someone who fits the description of the sketch.

Indiana State Police released a new rendering Monday of the man wanted in connection with the 2017 killings of two girls north of Indianapolis.
