Incest dad kills baby he had with his daughter, then commits suicide

An incestuous father who had a baby with his biological daughter is believed to have killed the infant in North Carolina before murdering the girl and her adoptive father 600 miles away and then turning the gun on himself.

Law enforcement officials in three states are working to untangle the chain of events that led to the deaths of four people, among them a seven-month-old boy.

Steven Pladl, 43, was discovered dead from a self-inflicted gunshot wound inside a car parked in Dover, New York, at 8.40am on Thursday. 

His biological daughter, whom he illegally married last July, 20-year-old Katie Pladl, was found dead in Connecticut along with her adoptive father, 56-year-old Anthony Fusco.

The baby boy named Bennett that Steven and Katie had together in September 2017 was discovered dead at a home in Knightdale, North Carolina, where the couple used to live, reported CBS17.

Steven Pladl was said to be still living in the home on Earlston Court. 

During a press conference, Knightdale Police Chief Lawrence Capps confirmed all three murders and Steven Pladl's suicide. 

 
Steven and Katie got together in 2017, after she decided to get in touch with her birth parents in June of 2016. 

Not long afterwards, Steven and Katie's biological mother, Alyssa, separated and Katie and Steven started their affair. 

In July 2017, the pair 'got married' and shared photographs of their lakeside union on social media. 

Katie gave birth not long afterwards to a baby boy. Since then, they had both doted over the newborn on Instagram. 

They were arrested in January 2018 when Alyssa discovered heir incestuous marriage and reported it to police.   

Both were extradited to Henrico County, Virginia, to face charges of incest, adultery, and contributing to delinquency of a minor.   

Steven was released on bond and ordered to remain in Virginia pending his trial and make no contact with Katie. The conditions of his bond were later amended to allow him to travel to North Carolina. 

Katie was released from jail in late February after posting $12,000 secured bond. Under the conditions of her release, she was barred from making contact with Steven and required to live with her adoptive parents, who resided in New York. 

In February, Alyssa told Daily Mail TV how she discovered their relationship in her 11-year-old's journal. 

After she and Steven separated, the 11-year-old switched between staying at her home and the home her ex-husband was in with Katie. 

In the entries, the 11-year-old depicted Katie as being pregnant and described Steven as 'Satan'. 

They wrote that because Katie was 'human' and Steven was 'Satan', their baby would be 'half-demon.' 

In March 2017, Steven presented Alyssa with the journal and said the 11-year-old was 'acting out'. 

Alyssa, who was horrified, said she thought it was his way of informing her of the incestious affair. 

She contacted police immediately but the pair carried on living together and in July, got married in front of Katie's adoptive parents and Steven's mother.  

The baby was born not long afterwards
