Manuela Rodriguez attempted to take her own life using the power saw after allegedly murdering her granddaughter , Rose Herrera . A Chicago woman has been charged in the killing of her 7-month-old granddaughter , who had her throat cut with a power saw after being suffocated with a sock and beaten to death . Police have said the baby girl , Rose Herrera , was killed Monday , apparently because she would not stop crying . The Cook County State 's Attorney 's Office said Tuesday that the baby 's 52-year-old grandmother , Manuela Rodriguez , was charged with first-degree murder in baby Rose 's death . An autopsy concluded that the baby was already dead when her throat was slashed . It also found that not only was the girl struck in the head with an object , but that she also likely suffocated on a sock that was ‘ placed in her mouth , ’ according to a county medical examiner 's log that includes the infant 's death . Rodriguez , who police say attempted to take her own life after the attack , was taken to a hospital for treatment for injuries that were not considered life threatening . The State 's Attorney 's Office said Rodriguez is scheduled to appear in court Wednesday . Police were called at around 9.40am to a multi-family home in the 2800 block of South Avers Avenue in the Little Village section of Chicago , where they discovered the lifeless body of the infant with 'visible trauma . ' The child was pronounced dead at the scene . Investigators said before the suspect took a circular saw to the child 's body , she tried to quiet her down by stuffing a sock down her throat . Following the killing , Manuela Rodriguez reportedly attempted to take her own life . She was rushed to Mount Sinai Hospital in a stable condition . Residents of the quiet street in the predominantly Hispanic Little Village neighborhood where Rose was killed said the Rodriguez had some health problems but was always pleasant . Officers found the child , identified by family members as Rosie , after being called Monday morning to a building on the city 's West Side ( pictured ) State child welfare officials said they had no record of ever being called to the brick home . Neighbors said the woman and her family were always polite and did not cause trouble . ‘ She would help everybody and if you needed a glass of milk or something she would give it to you , ’ said Maria Gentil , who has known Rodriguez for several years and said she was a doting grandmother . ‘ When my mother died , she went up and down the street asking for money for her funeral. ’ Ben Llamas works with the child 's father and drove him to the scene . Mr Llamas told the Chicago Tribune the father was upset but did not talk about what happened . His friend had moved in to that house about a year ago with a woman , Llamas said . The couple had a young child . ‘ At first , he was reluctant , but when the baby came , he fell in love , ’ Llamas said . ‘ He shows us pictures of that baby every day. ’ Neighbors said several people live in the home where the baby was found . ‘ They were really good people , ’ Francisco Arreola told the Chicago Tribune in Spanish . ‘ I would always see them and they were very happy . I never heard them fight or anything. ’ Tragedy : Police say the child 's killer tried to stuff something down the child 's throat to make her stop crying before using the saw .
