Police in New York City are investigating a grisly double murder-suicide in which they say a man decapitated his wife, slit the throat of their five-year-old daughter and then took his own life by hanging Wednesday night, just hours after the woman tried to get an order of protection.

According to the NYPD, at around 9.18pm officers responded to a 911 call requesting a welfare check inside an apartment at 151 West 121st Street in the Harlem section of Manhattan.

Upon entering the unit, officers found Yonathan Tedla, 46, Jennifer Schlecht, 42, and their five-year-old daughter, Abaynesh Schlecht Tedla, dead inside.

It is unclear how long the family had been dead before their bodies were discovered.

Schlecht’s heartbroken father, Kenneth Schlecht, 74, tells New York Daily News that his daughter’s marriage was unraveling, and that his son-in-law had threatened to ‘take them all out’ if Jennifer tried to serve him with divorce papers.

Spectrum News NY1 said neighbors described the couple and their young daughter as ‘the perfect family’.

Tedla was discovered in a bedroom, his wife in the bathroom, and their child in another bedroom, according to a press release from the police. The mother and daughter both had neck trauma.

The New York Daily News reported, citing unnamed sources, that Schlecht was found decapitated, with her severed head resting in her lap.

Her daughter suffered a cut so deep to her neck that she was partially beheaded.
