VIRGINIA, Minn. (AP) -- Katie Poirier's dentist testified in the murder trial of Donald Blom, saying material she used on Poirier's teeth 14 days before the woman's abduction matches that found in a tooth on Blom's property.
Dr. Melanie Meier of Duluth told the jury Thursday she filled Poirier's lower left molar -- known as tooth number 18 -- using the same process and bonding agent that prosecutors say was used on a burnt tooth found in a fire pit on Blom's rural Moose Lake vacation property.
Prosecutors are trying to convince the jury that the tooth and other fragmentary human remains found in Blom's fire pit came from Poirier.
A forensic dental expert, Dr. Ann Norrlander, testified Wednesday she believed the burnt molar was human tooth number 18 and, in her opinion, came from Poirier.
Prosecutors contend Blom, 51, of Richfield, abducted Poirier 19, of Barnum, from a Moose Lake convenience store where she was working alone shortly before midnight on May 26, 1999. Blom confessed but later recanted.
Meier testified she filled Poirier's tooth with a 3M bonding agent called RelyXARC, which she said was a relatively new product at the time.
The prosecution has the molar from the fire pit contained traces of an ingredient found in that product. The defense has said the same ingredient, zirconium, is in other 3M dental products that have been in use for years.
Also Thursday, prosecutors recalled the Minnesota Bureau of Criminal Apprehension forensic scientist who led the team gathering evidence at the crime scene the day after Poirier's abduction from DJ's Expressway Conoco. James Dougherty testified about the 148 pieces of evidence submitted for identification and testing.
