SAN ANGELO - Lab work began on Monday on the more than 400 children removed from the Eldorado polygamist compound.
State officials took DNA samples, involving cheek swabs from the children and their parents, hoping it will help sort out the confusing family relationships in the custody case.
The testing is being done at the San Angelo Coliseum where most of the children have been held since last week.
Child Protective Services Spokesman Darrell Ayzar says the process will likely take about half an hour per sample.
Officials expect the sampling to be complete by later this week.
