The lawyer for a man charged with criminal negligence in the deaths of his twin baby granddaughters is looking for answers.
Robert Sutherland wants to know if the infants suffered from a potentially deadly childhood virus.
He has sent a letter asking Ontario Crown Prosecutor Dan Mitchell if medical tests conducted on the bodies included screening for the virys called R-S-V.
Sutherland says he understands that it is a fairly common virus that generates respiratory arrest and death in young children under the age of four.
He says he sent the letter after receiving word of a near-fatal case of the virus in Thunder Bay.
Jerry Kerrigan of Grand Bend, Ontario faces charges in the deaths of the twin girls.
They died in a Thunder Bay motel room last month.
