A mother charged with killing four of her young children and their father smiled and posed for cameras, giving a double 'thumbs up' sign to a photographer as she awaited her first court hearing.

Isabel Martinez, 33, appeared before Gwinnett County Magistrate Judge Michael Thorpe Friday, one day after police said she stabbed five family members to death and seriously injured another child at a home in Loganville, Georgia.

Martinez is also in the country illegally according to US Customs and Immigration Enforcement spokesperson Bryan Cox.

Immigration authorities have placed a hold on Martinez, who is from Mexico and entered the US illegally.

Cox said this is Martinez's first encounter with immigration authorities and it is not clear how long she has been in the US.
