Arlington police confirm that the remains of a second body have been found Tuesday behind a house after human remains were first discovered in a nearby wooded area Saturday.
Police began investigating after the first remains were located Saturday in a wooded area near the intersection of East Sanford and Truman streets.
A man, who asked NBC 5 not to use his name, said he discovered a severed human head Saturday on a wooded trail with a note next to it, written in Spanish, that said "respect the group, four are still missing."

Although Arlington police say they only know of the two bodies, the man who found the head is terrified.
"I feel uncomfortable, anxious. I can't sleep. I can't eat. I eat a little and I get sick," the man said in Spanish.
