A Forsyth County Grand Jury considered about 45 cases last week.
Among those, suspects were indicted in at least five separate murder cases.
Forsyth County District Attorney Penny Penn said it is unusual to have so many cases, especially of such a serious nature, go at same time before a grand jury.
"I tried to reassure the grand jury that they don't live in a lawless county and that this is not typical," Penn said.
She added that prosecutors had a little extra time to work on cases since the last grand jury meeting in February.
In addition to the slaying of a grocery store security guard [see related story], indictments were handed down in the following cases.
Body of woman found in home
Jorge Montiel was indicted on one county of murder, two counts of felony murder, two counts of burglary and one count each of aggravated sexual battery and aggravated sodomy.
The charges are in connection with the killing of 34-year-old Maria Hernandez-Reyes in October at her home on Park Street in Cumming.
Court documents show Montiel is accused of strangling the woman to death. Her body was found Oct. 13, authorities said, by a tenant who rented a room from her and her husband.
Authorities obtained warrants to arrest the suspect, who is thought to be between the ages of 22 and 25, shortly after Hernandez-Reyes was killed, though they have not been able to locate him.
Penn said Montiel is thought to be in Mexico, making an indictment necessary in order to extradite him to Georgia.
Six-year-old beaten to death
Eder Antonio Acosta was indicted on one count each of murder, felony murder, aggravated battery and first-degree cruelty to children in connection with the July 16, 2009, beating death of 6-year-old Bryan Guzman-Moreno.
Acosta, 22, of 1840 Valley Lane, was arrested two days after the death.
At the time, he was the live-in boyfriend of the special needs child's mother, Laura Moreno.
The case caught the attention of the state Office of the Child Advocate and Division of Family and Children Services, which received at least four reports of abuse at the home before the child died.
The most recent report had been filed in January 2009 by Guzman-Moreno's 11-year-old brother. The boys did not have the same father. Acosta is the father of a younger sibling, who at that time was 1.
Violent attack on Kelly Mill Road
Martin Rangel Nava, 27, of 318 Kelly Mill Road, was indicted on one count each of malice murder, felony murder and aggravated assault.
Nava was arrested May 19, 2010, in connection with an altercation that resulted in the death of Francisco Celestino-Sanchez. Authorities said the two had met in jail.
On May 7, 2010, Cumming Police came to Celestino-Sanchez's Kelly Mill Road home (same address as Nava's), where they found him bleeding and unconscious in the driveway with a garbage bag full of trash and beer cans on his head.
Celestino-Sanchez was taken to North Fulton Hospital in Roswell, where he died of his injuries the following week.
Court documents show that Nava, a Mexican national, was placed on hold at the time of his arrest for U.S. Immigration and Customs Enforcement.
He was also being held due to a Cherokee County bench warrant.
Fatal arson in south Forsyth
Jill Smith, 34, and Peter Delaney, 37, were indicted on one count each of murder, felony murder and first-degree arson in connection with a fatal Oct. 22 house fire.
The blaze at 5540 Kennemore Drive, off Union Hill Road, claimed the life of Smith's husband, Michael Smith.
Officials have said Jill Smith and Delaney were having an affair. They and Michael Smith were inside the house at the time of the blaze, as was Jill Smith's son.
Earlier this month, Smith and Delaney were denied a second request for bond.
During a hearing March 3, Smith's attorney also sought medical care because Smith is reportedly more than four months pregnant.
Attorneys for the suspects have maintained their clients' innocence, questioning the evidence in the case.
