DELPHI, Ind. — Indiana State Police have released an artist’s composite sketch of a man considered the main suspect in the killings of two northern Indiana girls.

The sketch released Monday depicts a white man with a prominent nose and a goatee who’s wearing a cap and what appears to be a hooded sweater. Police said the suspect has reddish-brown hair, stands between 5-foot-6 and 5-foot-10 and weighs between 180 and 220 pounds.

Investigators are asking the public to study the man’s facial features and contact them with any information on him.

Sgt. Kim Riley says the sketchwas created by an artist from information collected by all the agencies, including the FBI, involved in the double-murder investigation.

Fourteen-year-old Liberty German vanished with 13-year-old Abigail Williams on Feb. 13 while hiking a trail near their hometown of Delphi, about 60 miles northwest of Indianapolis. Their bodies were found the next day in nearby woods.

Investigators released two grainy images in late February of a man they consider the main suspect in the killings. They also released audio of a male saying “down the hill.”

That evidence came from German’s cellphone.

In March, Mike Patty, grandfather of Liberty German, urged people to study those images and come forward with any information.

Patty said then that anyone who noticed that a friend, relative or acquaintance had recently changed their appearance such as by shaving a beard or who is acting uncharacteristically strange should pass that on to authorities through a tip line. He urged people not to second-guess themselves about whether something they’ve noticed is significant.
