under a microscope, scientists could see that the fragments were different shapes and sizes. the surfaces were corrugated and the composition of the metal varied from piece to piece. they were made of various types of steel, various grades of steel, various grades of brass. the unique shapes and the fact some were hollow were a clear indication of their origin. what that means to me is it s a piece of metal projected through the air. when it s projected through the air, metal, molten metal, when projected through the air is cooling very, very rapidly. with the air current as it goes through the air it dries to a soccer ball round shape. so investigators knew the killer was probably a machinist, someone who worked with metal at high heat on a lathe. arlene jensen was a seamstress and there were no metal fragments like these in her workplace.
oftentimes true. but i will say that one stereotype that i think gary ackley is a perfect example of is a domestically violent woman-abusing killer. prosecutors believe ackley had access to arlene s apartment key and used it to enter her home late one night after she was in bed. the autopsy results aren t clear about how he killed arlene, but the evidence suggests she was killed while in bed. metal fragments dropped from ackley s clothes on to the sheets, fragments he couldn t see. he stayed in arlene s apartment long enough to smoke two cigarettes and wash his hands. then he hid the blood-stained sheets with the comforter.
the steel had the exact same combinations of iron, manganese and chromium. in the brass, copper and zinc were found in identical amounts. and all the samples had equal amounts of cerium, part of a compound used to ignite an oxyacetylene torch, a common item in machine shops. we examined all of them and could see the pattern that regardless of where they came from, they were basically the same kind of metal fragments, machining fragments. this proved that both arlene jensen and stephanie dittrick were killed by the same man. the science is starting to really catch up to the bad guys now. a serial killer was on the loose in the seattle area. he had to be stopped before he could kill again.
believed was her meddling in the way he raised her grandchildren. and the way he treated her daughter. the offensive thing about stereotypes, i think most people would agree, is that they re oftentimes true. but i will say that one stereotype that i think gary ackley is a perfect example of is a domestically violent woman abusing killer. prosecutors believe ackley had access to arlene s apartment key and used it to enter her home late one night after she was in bed. the autopsy results aren t clear about how he killed arlene, but the evidence suggests she was killed while in bed. metal fragments dropped from ackley s clothes on to the sheets, fragments he couldn t see. he stayed in arlene s apartment long enough to smoke two cigarettes and wash his hands.
arlene jensen was a seamstress and there were no metal fragments like these in her workplace. the next clue came from an unlikely source almost 40 miles away. campers in a national park outside of seattle found a decomposed body of a young woman partially buried in a shallow grave. a leopard skin jacket was on the ground nearby. through dental records, the victim was identified as 29-year-old stephanie dittrick, an administrative assistant who was reported missing several weeks earlier. she was last seen at a fourth of july party. stephanie was at her residence on july 4th and there were people firing fireworks around the area and sounds like she was having a good time with the neighbors. stephanie told friends she planned to go camping, but no
