An emergency medical technician has been jailed for three months for deliberately delaying her response to treat an eight-month-old girl, who died a day later.

Ann Marie Thomas, 48, was sentenced on Thursday for waiting in her ambulance in Detroit, Michigan, when she got a 911 call about a toddler who was struggling to breathe.

Thomas arrived on the scene on May 30, 2015 where baby I'Nayah Wright-Trussell was suffocating, but she hesitated.

The child, who was suffocating at the time of the incident, was also a victim of horrific physical abuse, for which her mother was later imprisoned.

Although Thomas was parked less than half a mile from the home she delayed arriving, prosecutors said.

Eventually another EMT was sent to aid the child. Thomas was fired a month after the incident.

The baby died the following day of suffocation. Her mother Janee Wright-Trussell, pictured above, was charged with homicide and child abuse in her death

In court she told a judge she was 'innocent'.

'I can't believe I'm sitting here today facing these charges,' Thomas told Judge Roberta Archer before she learned of the sentence Thursday.

'I did nothing wrong your honor. I did my job,' she added.

She was sentenced to three months behind bars and two years of probation for neglect of duty. She was also offered mental health services.

Two internal investigations were conducted in the incident.

A jury convicted her on February 28.

The baby was revived on the day of the incident but died the following day, according to Click On Detroit.

The victim's family alleged in a lawsuit that Thomas told dispatch she didn't want to be there for '10 minutes doing CPR, you know how these families get.'

Assistant Wayne County Prosecutor Matthew Penney said to the judge: 'I didn't realize Ann Marie Thomas was the victim in this case. Her entire function was to get there lickity-split.'

'When we entrust EMS workers - individuals who have certain obligations to respond to emergency situations - we have an expectation that they are going to act in accordance with what they need to do to get there,' Archer said.

'This situation became very real with the death of this child,' he added.

A medical examiner ruled the child's death a homicide with suffocation as the cause of death. Other injuries and bruises were found including multiple rib fractures in various stages of healing, bruises on the bowels, liver, spleen and both lungs.

The baby’s mother Janee Wright-Trussell was charged with homicide and child abuse in her death, according to Click On Detroit.

She pleaded guilty last year to voluntary manslaughter and was sentenced to eight to 15 years in prison.
