33-year-old Isabel Martinez was arrested in the stabbing death of her husband and four children on Thursday at their Loganville home in Georgia. A fifth child survived the incident but is seriously injured. Gwinnett County Police have now identified the victims in the horrific family murder.

Father and children identified by police in Loganville stabbing

Martinez’ husband, Martin Romero, 33, was killed along with Isabela Martinez, 10, Decota Romero, 7, Dillan Romero, 4, and two-year-old Axel Romero. The fifth child, Diana Romero, 9, has been hospitalized at Children’s Healthcare of Atlanta where she is said to be in a serious but stable condition.

While a motive has yet to be established, police say Martinez was allegedly depressed over the recent passing of her father in Mexico. Letty Perez, one of the Martinez’s neighbors, told WSB-TV that the mother had said her father passed away some months ago and that she was suffering from depression.

Perez said they would go to her house sometimes to pray for her dad. Perez did say that apart from the recent depression over her father, Martinez seemed to be a normal and regular mother, adding that she had joined their family at church the previous weekend.

CBS 19 reports that another neighbor, Pedro Ramirez said Martinez had seemed happy until the death of her father. He said she began acting “a lot meaner” following the news of his passing and that she was upset she couldn’t travel to Mexico to attend his funeral.

Ramirez said Martinez said she kept “seeing things.”

The Atlanta Journal-Constitution reports that Martinez and her family had moved to Loganville from Chicago a month ago, where they have relatives. One man at the home on Thursday identified himself as Romero’s brother. He said he had spoken to his brother on Wednesday and nothing seemed to be wrong at the time.

Timeline of the Gwinnett County family murder

According to Gwinnett County Police, they received a 911 call from Martinez at 4:47 a.m. on Thursday and after discovering the bodies of the father and four children in the Loganville home, the mother was arrested early Thursday.

Martinez is now facing six counts of aggravated assault, as well as five murder charges and is currently being held by U.S. Immigration and Customs Enforcement. Police further said Martinez may have been in the home with the dead family for a number of hours before she called 911. Cpl. Deon Washington of the Gwinnett County Police said it was reasonable to believe the family had lain dead in the home all night.
