Episode 122. 81 Days.

Ward baby here with another episode of murderous minors.

In lots of families everywhere, older siblings are a backbone, integral to a structure whose foundation generally consists of exhausted parents.

Even three year olds can grab their newborn siblings pacifier from a bag and as the years go on and the family grows, caregivers often look toward big brothers and sisters more and more to lend a hand.

Many don't mind and some may even pitch in on their own, but this week on murderous minors we look at a case where a child's helpfulness seemingly switched to resentment as no one noticed.

I will be talking about fatal harm against very small children as well as animal abuse in this episode, so please be advised.

We don't know a lot about the early years of Nicholas James Kedrowitz who was 13 years old back in May of 2017 when this case began, but we do know some.

We know that the now 17-year-old had lived in Elizabethtown, Indiana and just about finished grade school at Rock Creek Elementary before moving to Richmond, Indiana in 2014.

He had what his mother referred to as a quote, mild learning disability, but was a Cub Scout and Boy Scout and participated in activities through his church.

By 2017, Kedrowitz and his family had settled in Osgood, Indiana, about 60 miles south of Cincinnati with his mother Christina McCartney, who said in 2018 interviews that he was spontaneous in quote, every mom's dream child.

I didn't have to ask him to help with the kids he would just do it, he would sing to them, read them books.

The kids, as McCartney called them, were almost two-year-old Desiree and one-year-old Abigail, who along with Kedrowitz were her biological children, as well as almost one-year-old Nathaniel Ritz, the son of her fiance Steven.

Both adults and all four of the children lived together in a home on the 200 block of South Maple Street in Osgood, Indiana.

McCartney, who has a master's in psychology, granted multiple interviews in 2018, including some with the local news, one with the republic.com, and she also appeared on the Doctor Phil Show, so we will be covering most everything she revealed at those times.

Court affidavits reported on by Julie McClure indicate that on May 1, 2017, McCartney told police that when she got home from work, her oldest child, 13-year-old Nicholas Kedrowitz told her that Desiree McCartney, his 23-month-old half-sister, wasn't feeling good and wasn't talking to him.

Her fiance Steven Ritz told police that the two babies Abigail and Nathaniel had been in the living room crying, but that Desiree was in the bathtub, so he asked Kedrowitz to grab her PJs and diaper and get her dress for bed.

When Ritz got back, he said that Kedrowitz was crying and holding a lifeless Desiree wrapped in a towel. He said she wasn't breathing.

About five minutes later is when McCartney arrived, coming home to the nightmare scenario of having to perform CPR on her toddler just after entering her home.

Kedrowitz told police some very specific things when they arrived, such as Desiree had gotten out of her clothes and into the bath on her own, with the water at about chest level once she sat down.

The teen told police that the toddler had vomited while in the tub, so he left her unsupervised for up to five minutes to retrieve some baby wipes.
