The father, Elvis Noe-Garcia, was charged with two counts of murder and aggravated assault. Another man was originally charged in the stabbing, but the charges have since been dropped.
RAW VIDEO: Gwinnett Police Fatal Stabbing Press Conference
Police responded to a quadruple stabbing at a home on Bridle Path Drive outside Lawrenceville on Wednesday, Gwinnett police Cpl. Jake Smith said. Officers made the gruesome discovery at about 6:30 p.m., Smith said.
The boys, 1-year-old Edward Garcia and 3-year-old Bradley Garcia, were found in the basement of the home, Smith said. He said another 3-year-old boy was also stabbed. The surviving child, who family members said was Bradley's twin, was flown to Children's Healthcare of Atlanta at Egleston, where he was in serious condition, police said.
Garcia, 23, was also found stabbed. He was taken to a local hospital in serious condition.
The next day, 28-year-old Antonio Cardenas-Rico, was charged with two counts of murder. Just days before, Garcia made a threat complaint to police about a man with the last name "Cardenas."
Channel 2 obtained a Feb. 2 report in which Garcia identified the man as his ex-girlfriend's boyfriend. He said the man called him with the message, "I will kill you."
But Smith said Saturday murder charges against Cardenas-Rico were dropped. Though, he remains in police custody on drug charges and an immigration hold.
At a 5 p.m. press conference Saturday, Smith said police discovered discrepancies between the evidence and Garcia's statements and his alibi. After re-interviewing witnesses and reassessing the facts, police determined that Garcia was responsible for his sons' killings. Smith said he stabbed himself to look like a victim.
"The whole story involving the involvement of Cardenas-Rico was entirely fabricated," Smith said.
He said the three have been involved in a custody battle over the children.
Smith said Garcia has been uncooperative since being charged.
Garcia was being held without bond pending his next court appearance.
