A Shelton woman has been arrested after allegedly leaving her three children \u2014 all under the age of 6 \u2014 home alone, one of which was a 5-month-old child who later died at the hospital. Jessyka\u00a0Oliveira, 30, has been\u00a0charged\u00a0Tuesday, April 2,\u00a0with\u00a0three\u00a0counts of\u00a0risk of\u00a0injury to a minor and one count of interfering with a\u00a0police\u00a0officer\u00a0in connection with the alleged incident that occurred in December 2018. No other charges are expected in this case, according to local law enforcement. \u201cEMS and Shelton\u00a0police were dispatched to a residence in the downtown area of Shelton for a medical call,\u201d said Shelton Police Detective Christopher Nugent.\u00a0\u201cMedical attention was administered to a 5-month baby,\u00a0who was later pronounced deceased at the hospital.\u201d Nugent said that\u00a0Shelton\u00a0police\u00a0conducted an investigation into\u00a0the incident and determined that,\u00a0approximately two hours prior to the medical call,\u00a0Oliveira left three children unattended at the residence for a short period of time. The children were all\u00a0younger than\u00a0the age of 6. \u201cDetectives also determined that Oliveira was not truthful during her initial interviews,\u201d said Nugent. According to an eight-page arrest warrant written by Detective Richard Bango, police and EMS were called to Oliveira\u2019s Perry Avenue home about 11:20 a.m. on Dec. 20, 2018, for an unresponsive 5-month-old girl. The warrant says Oliveira has three other children, two of whom were also home at the time \u2014 a 4-year-old and 1-year-old. Oliveira told police she had put the baby, who had been congested with cold-like symptoms, in a bassinet to sleep about 9:30 a.m. She said she tended to the two other children as the baby slept, but checked on the infant about 11 a.m. and noticed she was blue, her eyes were dark and she wasn\u2019t breathing. Oliveira called 911 and performed CPR until the arrival of police and EMS, who were able to get a pulse. The baby was taken to Griffin Hospital, then Yale New Haven Hospital. The warrant says the child had a respiratory virus in her lungs. The baby died at 1:43 a.m. on Christmas Day, according to the warrant. An autopsy police received last month listed the cause of death as undetermined. A medical examiner told police he could not definitively say what caused her death \u2014 the respiratory virus, bronchopneumonia or pneumonia the baby contracted at the hospital. An investigation found that two hours before the medical call, Oliveira left the three children alone in the residence for \u201ca short period of time,\u201d Nugent said. Detectives said Oliveira was untruthful during her initial interviews. The warrant says Oliveira initially told police that earlier that day, she had a friend watch the three children as she took her oldest child, a 6-year-old, to school. However, when police questioned the friend, she said Oliveira had asked her to lie to them, and showed cops Facebook messages backing up her story. She was released from custody after posting a $5,000 bond. She appeared at Derby Superior Court Wednesday, where Judge Peter McShane continued the case to April 16, at which point it may be transferred to Milford Superior Court, which handles more serious cases.
