DNA Test after Death

Dna Cremains Ashes Heat Process

Q.My sister was involved in a car crash, and she lost her unborn child. The autopsy report revealed she was 18 weeks and 1 day pregnant. A wrongful death suit has been filed for the loss of her child, however, there is a question of who the father is. My sister chose to have her stillbirth cremated, and I was wondering if there was a way DNA testing could be done since the baby was cremated. If so what are the options?

(Mrs JB, 10 September 2008)

A.

I want to offer sincere condolences to your sister and your family. I wish I could offer you a more hopeful answer but unfortunately, the high heat of the cremation process destroys DNA. This means it is extremely unlikely that you would be able to make an identification of the father through DNA testing of the ashes. When a cremation is properly performed, the heat is extreme to the extent that no living material exposed to the heat can survive it.

Interestingly enough, one part of the body that is weakened but still intact to some degree following cremation is a person's teeth. Virtually all properly performed cremations will ultimately pulverize the teeth though, so there is little chance of intact DNA. However, on the rare chance there was a tooth, it could be possible to use this for paternity identification. Given the age of the foetus at death, there would have been teeth already forming, despite the fact they had not yet emerged.

Generally, DNA testing is quite reliable on a deceased person prior to cremation but it is once the DNA is exposed to the heat of cremation, it does not survive intact. I am not sure if this is any consolation, but I can say that your sister is not alone in her quest to determine DNA from ashes. In fact, the question is a common one heard at funeral agencies but at this point in time, the answer is not favourable to testing.

Still, while there is not yet any reliable, accurate form of testing for DNA in cremated remains, it is not to say that this kind of test won't become available in the future. I can appreciate that your sister may need to put closure on the paternity aspect of her dead child, but the only advice I can provide is to try to find a way to emotionally move beyond the issue, through family and friendship support or through counselling. Your sister can still stay aware of the newest developments in forensic science and DNA testing – perhaps one day testing will be able to include ashes.

How can I prove that 2 people, a man and a woman, are actually brother and sister, if the father has died many years ago and his/her mothers is different ?

My son was murdered by his girlfriend and she is pregnant. The coroner has his dna. There is speculation the baby is not his. How do I go about testing the dna?

I lost my daughter last year. Since her passing there's been multiple statements made regarding her paternity. I do have a friend who believes he is her father. And apparently the man who was helping to raise her, signed her birth certificate and all that is now saying hes not her father. So id really like to find out if theres a way to do a paternity test?

Our Son was killed in a Violent Motor Cycle wreck , his girlfriend was pregnant when he passed away. She had a little girl 1 moth later. We just met her after 6 years. She looks just like me and my Son. Me and her did a DNA. IF she is my Son's daughter would she be able to have his last name.I would approve of this if she is his. Thanks

I was adopted over 40yrs ago and never knew my biological father until approx 5yrs ago when I managed to locate him. When I met him he confirmed that he believed he was my natural father. Sadly he passed away shortly after meeting him. Now I am left wondering whether he was actually my father. I assume dna testing is the only way to confirm that he was my biological father. Clearly this is now difficult with his passing but perhaps not impossible. When I met him he told me he had been in trouble with the law and had served a short custodial sentence. Can I match my Dna with that of my suspected father by gaining access to the Dna taken from him by the police? Your help in this matter would be very much appreciated

Cat - Your Question:
I was told that the man that I called Dad wasn't my father. The man that is supposed to be my father is die in 2012 but I have some of his ashes. Could I do a DNA test on his ashes?

Our Response:
No, that ashes would probably not be sufficient to perfom sufficient DNA analysis to establish/rule out paternity.

Rmebraatt - Your Question:
My son passed away and I have his ashes and baby teeth, is there a way to get his DNA profile? I was adopted and told the search would be better if I had male DNA of a relative.the only blood male relative is my son and he passed away at 15 from suicide.any help or where to direct me would be appreciated, this has been my focus since he passed because for some weird reason, I want to find more biological family.

Our Response:
Ask at a DNA testing clinic whether there is any dried blood left on the teeth that might just be suffficient for DNA profiling. Pulp is the main source of DNA in teeth but it doesn't survive very long (6 to 12 months) once it's no longer in the mouth.

Lost - Your Question:
I have 3 older sisters who share the same mother and father. When I was conceived, my mother and her husband were legally separated. My mother has always told me that her husband was not my father, and he told his 3 children I wasn't, either. The problem I have is he is listed on my birth certificate as my father & at birth, I was given his last name. I know the name of the man who my mother said was my father, and he was married, too. He said I was his daughter, as well, but as a child, I was continually told by my dad's wife that her husband was not my father. Due to this reason, I suffered a lot of physical and mental abuse from her. The abuse started when I was about 3 years-old and it has affected me deeply. I grew up afraid of people and I trusted no one - not even my mother! My father passed away suddenly when I was 11 years-old. At his funeral, I wasn't acknowledged, and I received a battery of dirty looks from her family. Over 40 years have passed, and I am still deeply troubled. I now have more years behind me, than ahead of me and before God calls me home, I'd like to know was the man who my mother said was my father really my biological father? Fortunately, I am close to his sister's children. Is there a way to compare my DNA with that of one of my paternal cousins to see if we are really related? I just need to know.

Our Response:
You should ask at a DNA testing centre whether a relationship between your possible father's nieces and you would be sufficient to tell this.

My daughter's grandma called to see if my daughter could go to mexico to give her DNA. She gave no reason why she needed. I can only guess that her (grandma's) son went missing about 5 years ago and they found a body. But I don't want my daughter going to mexico because of the violence. Can they (the morge )not use her (grandma's) DNA of one of her other children? Thank you

FatherUnknown - Your Question:
My mother passed away recently and someone came to me saying that they thought their dad could be my father. All my life my paternity has been a question and I frequently am asked what my ethnicity is. On my birth certificate my 2 older siblings father is listed but I have always been told he's not my biological father. My question is can the girl who approached me and I have a dna test done together to establish if we are half sisters? Both of our mothers have passed away. Thanks.

Our Response:
There is nothing to prevent you from finding a DNA testing clinic and paying for this to satisfy your mind.

I was curious to find out how I could get a DNA test done on myself to find out what ethnicity I am. My dad whom I have been calling dad for as long as I can remember, is not on my birth certificate never has been. I want to know if there is any test I cam do to prove he is not my dad due to how he treated me growing up and how different he still treats his other children from whom have my mothers last name and not our dads last name. From what I hear from others and characteristic wise they is a great chance he is not my father.?????

Our Response:
A search on the internet will bring up DNA testing centres in your area. A test may establish your ethnicity but unless you have a sample from the man you call your dad, it may establish your relationship with him.

Question: Unfortunately, My daughter was killed a few months ago. I was a single mom for her entire life. She never (admitted) to be curious as to who her father was. Again with the word 'Unfortunately', but, unfortunately the man we (I) think the father is is also deceased. Can we determine paternity with both the child and alleged father deceased? His (the alleged father) mother is willing to help if she can.

Lost - Your Question:
Looking for closure. My mother said she was raped, and did not know who my father was. As time went on I discovered through family rumors it could have been her step father. She stuck to her story of not knowing. Jump to 20years ahead. My mother passed away in the 90's. She was cremated. Her step sister called me up stating she believed I was her half sister, she stated things didn't make sense. Her father denied allegations before his passing in 2000's. She is willing to do a DNA test. Who else do I need to do the test? Only his other daughter ( her full sister) knows about her finding me. I have told my aunts and an uncle. My mother had no more children. Would like to involve as few people as possible and find out the truth.

Our Response:
If you both take a DNA test that should be sufficient to see whether you are related. We're assuming your mother and her step sister don't also share the same mother.
