Murderers sometimes dispose of bodies in zipped suitcases in an attempt to conceal their crimes. In these cases, the species of insects found and their succession patterns are typically different from those found on exposed corpses due to hindrances or delays in colonization. Here we report a case in which an unidentified female corpse was found in a soft-shell suitcase in a wetland area among some reeds in Guangdong, China on 13 May 2018. The suitcase was unbroken and zippers were well-sealed. The victim was a young woman, naked, and curled up in the suitcase. The insect evidence we collected include (i) pupae and empty puparia of Chrysomya nigripes (Aubertin) (Diptera: Calliphoridae) and Fannia canicularis (Linnaeus) (Diptera, Muscidae), (ii) larvae, pupae and empty puparia of Megaselia scalaris (Loew) (Diptera: Phoridae) and Hermetia illucens (Linnaeus) (Diptera: Stratiomyidae). According to this insect evidence, we estimated the PMI as 56 days. Bhadra et al. (2014) show that larvae of Calliphora vomitoria (Linnaeus) (Diptera: Calliphoridae) and Calliphora vicina (Robineau-Desvoidy) (Diptera, Calliphoridae) can colonize carcasses concealed in zipped suitcases. Although the size of the zipper (7mm) in this case is larger than that described in Bhadra et al. (4mm), we did not find Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae), Chrysomya rufifacies (Macquart) (Diptera: Calliphoridae), or Lucilia sericata (Meigen) (Diptera: Calliphoridae) which usually colonize fresh corpses in this area. Therefore, we deduced that the victim may have been killed in winter. After the crime was solved, the murderer confessed that he killed the victim on 5 January.
凶手有时会将尸体装在拉链行李箱中，试图掩盖罪行。在这些情况下，由于殖民地化受到阻碍或延迟，发现的昆虫种类及其演替模式通常与暴露在尸体上的昆虫种类不同。在这里，我们报告了一起发生在中国广东的案件。2018 年 5 月 13 日，在一个湿地地区的芦苇丛中，发现一具装在软壳行李箱中的身份不明的女性尸体。行李箱没有破损，拉链也密封完好。受害者是一名年轻女子，裸体蜷缩在行李箱中。我们收集的昆虫证据包括：(i) 绿蝇（Aubertin）（双翅目：丽蝇科）和厩腐蝇（Linnaeus）（双翅目：蝇科）的蛹和空蛹，(ii) 巨蚤（Loew）（双翅目：蚤科）和家蝇（Linnaeus）（双翅目：Stratiomyidae）的幼虫、蛹和空蛹。根据这些昆虫证据，我们估计 PMI 为 56 天。Bhadra 等人（2014）表明丽蝇（Linnaeus）（双翅目：丽蝇科）和厕蝇（Robineau-Desvoidy）（双翅目：Calliphoridae）的幼虫可以在拉链行李箱中隐藏的尸体上殖民地化。虽然此案中拉链的尺寸（7 毫米）大于 Bhadra 等人描述的（4 毫米），但我们没有发现丽蝇（Fabricius）（双翅目：Calliphoridae）、红头丽蝇（Macquart）（双翅目：Calliphoridae）或丝光绿蝇（Meigen）（双翅目：Calliphoridae），这些蝇类通常在该地区的新鲜尸体上殖民地化。因此，我们推断受害者可能是在冬季遇害。在犯罪被侦破后，凶手供认他于 1 月 5 日杀害了受害者。
