DELPHI, Ind. (AP) - 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.

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 (100 kilometers) northwest of Indianapolis. Their bodies were found the next day in nearby woods.
