a Las Vegas jury has condemned a 22-year-old man for stabbing a 3-year-old girl to death and seriously injuring her 10-year-old sister on Jan. 22, 2003.
Beau Santino Maestas pleaded guilty to charges of murder and attempted murder in the attack that killed Kristyanna Cowan, 3, and paralyzed her half-sister, Brittney Bergeron, 10, from the waist down. Investigators say the attack by Maestas, then 19, and his sister Monique, who was 16 at the time, was spurred by a drug deal gone bad. Police say the stabbing was provoked when the girls' mother, Tamara Bergeron, and her then-boyfriend, Robert Schmidt, sold them salt instead of methamphetamine.
