arsenic concentration was also high. If saline water like the sea water about one litter was poured into another green 50-kg can, and then dried, sodium concentration could be explained, but the sea water should take the mass ratio Na:Mg:Ca=100:12:4, which was significantly different from the ratio in **Table 2**. Based on the discussion at Section 3 and the present section, the paper cup arsenic oxide powder (1) was taken out from another green can imported from the same industry, but this green can was once exposed to saline water containing Na, Mg,

It is known that arsenic green 50-kg cans were imported from China twice in a year for total 10 years. The M's green can was one of the 60 cans imported at the same time by a ship, known by the shipping mark on the can. At the top, 10 or 15 cans were sold in Wakayama city in a month, and consequently at least more than one hundred cans were sold in Wakayama city

Starch was found for several arsenic oxide powder evidences using infrared (IR) analyses twice and iodine-starch tests twice. M's brown tupper (5) and T's milk can (6) results were contra‐ dicted as shown in **Table 2**. The paper cup (1) did not contain starch, and if the sentence was correct, starch powder mixed in the arsenic disappeared when taken by the paper cup.

Barium is not a light element but was found in several arsenic oxide evidences. Barium was an impurity element in SiO2 for M's brown tupper (5), because barium was not water soluble. Barium was an impurity element of Ca for T's milk can (6), because it was water soluble; calcium was due to the cement. However, the barium in paper cup (1) has not been analyzed whether water soluble or not. Based on these fact, Osaka Electro-Communication University and Hiroshima University, who performed forensic analysis according to the order of judge in 2001, concluded that paper cup arsenic oxide (1) was identical to either M's brown tupper (5) or T's milk can with the probability of 80% [47]. But this was wrong, because the concen‐ tration of arsenic was higher for paper cup than those of (5) or (6); also because of the discussion

I have published comments on the forensic analyses on Wakayama arsenic poisoned curry [2, 34, 35, 38, 40, 42, 44, 47–55], and revealed many false and truth-hiding reports step by step. Nakai of the Tokyo University of Science published papers in order to refute the above comments, but the refutations were not successful, and recently he has kept silence. The prosecutor sought some authoritative professors who could write documents against Kawai, but failed to find. The earlier discussion in the literature was cited by Chemistry Views [56],

The false forensic analyses were documents of National Research Institute of Police Science, of the Tokyo University of Science, of both Osaka Electro-Communication and Hiroshima Universities, and of the hair analysis of St. Marianna University School of Medicine. These four forensic reports had main role in the death penalty of Mrs. H. Forensic analysis reports of other
