ISHI 28 Workshop: Towards Better Solutions for Body Fluid Identification

Although techniques for DNA analysis of forensic samples have evolved considerably in recent years, the methods used to identify particular body fluids in forensic casework have remained relatively unchanged over the same time period. This year, one of the workshops offered at the International Symposium on Human Identification (ISHI; to be held in Seattle from October 2-5), will be focused on current and emerging techniques for body fluid identification that promise change—applying molecular genetics and proteomics analysis to the problem of body fluid identification.

According to the ISHI conference website, the purpose of the workshop is to “highlight current serology methods using critical case examples while also exploring emerging methods that could complement or replace these traditional techniques”. Continue reading

A Cold Case, A Mystery, and DNA

“How do you like the name Jack?” the woman on the phone asked.

She told Mrs. Fronczak that it was time to take the baby to the nursery (at that time newborns did not stay in the room with the moms), took the baby, and left. A few hours later, another nurse came into the room to take young Paul to the nursery. It was then that everyone realized a mother’s worst fear: Her infant had been stolen.

Authorities were able to determine how the woman left the hospital and that she got into a cab, but they were never able to find the woman. However in 1965, a small toddler-aged boy was found, abandoned outside a store in New Jersey. Blood tests were not inconsistent with him being Paul Fronczak (DNA testing was not available), and there were no other missing children cases in the area that were matches. The little boy was sent to Chicago as Paul Fronczak and the case was closed.

However, as an adult Paul Fronczak, began to suspect that the couple who raised him were not his biological parents, and in 2012 Paul underwent DNA analysis to test his suspicions. The results showed that indeed, he was not the biological son of Dora and Chester Fronczak. His next step was to enlist the help of a genetic genealogist to assist him in finding his true biological parents and his identity.

By conducting “familial searches” using commercially available DNA databases like 23andMe and AncestryDNA and many resources, the genealogist’s group found a match to his DNA on the east coast. Further ground work, discovered that this family was indeed Paul’s…now Jack.

The knowledge of Jack’s true identity, didn’t bring with it a joyous union of the adoptive family who had raised and loved Jack (as Paul) with the biological family who had pined for him over the years as many might imagine. Continue reading
