I read a fascinating article called "A Calculated Arson" written by fire scientist, John J. Lentini John J. Lentini written in April 1999 in a journal called, Fire and Arson Investigator  ten years after Mr. Han Tak Lee was convicted of murdering his daughter by setting a cabin on fire in PA. Mr. Lee was a Korean immigrant whose daughter had mental disabilities and under the advice of others, decided that the best thing for his 20 year old daughter, Ji Yun Lee was to take her to a Christian retreat camp (Hebron Camp) ran by Korean Assembly of God Church in Stroud Township, Pennsylvania away from New York and into the Poconos Mountains of PA.
"A Calculated Arson"

Represented by respected attorney, Peter Goldberger, Goldberger argued to the Federal Circuit Court of Appeals (3rd Circuit) in Philadelphia that fire science has evolved over the last 30 years and what was at the time considered good science, has since been debunked and is now considered junk science. Expert Lentini probably knew in 1989 that the "fire experts" who testified against Mr. Lee did not know what they were talking about or worse, that they were so desparate for a conviction that they make up a story that fits the evidence. Mr. Lentini provided a 41 page affidavit in support of granting Mr. Lee an evidentiary hearing.
Mr. Lee seeks hearing--"new" science

The article points out some things that do not make sense. Supposidly, Mr. Lee, used 62 gallons of heating oil and 12 pounds of gasoling; started the fire in 8 or 9 different places (called, points of origin), yet did not get burned himself.  All in a 1000 square foot cabin. . .hmmm. Also the expert at the trial said that there was fuel, in some places, 5 inches deep--on a flat surface--and that "floors don't burn" yet temperatures were as hot as 1,500-1,600 degrees and burned 7788.28 pounds of combustible material. Say what?  Oh, and the expert at trial said that he investigated 15,000 fires.in 20 years, which comes to 750 per month or about 15 a week. Mr. Lentini says that a very busy fire invetigator may do 5,000 in his entire career or 15 a month. Lots of other stuff too, but this is what I understand most easily and can recall without rereading the article over and over.
