A man was taken into custody on January 29, confessing to have killed his parents because they asked him to take the family dog for a walk.

The suspect,  Benno Neumair, 30, was taken into custody on January 29. His parents,  Peter Neumair and Laura Perselli, who are both teachers, went missing in the city of Bolzano in the northern Italian province of South Tyrol earlier this year.

According to Mail Online, Laura’s dead body was later found in the Adige river with signs of strangulation while her husband’s body never surfaced, although traces of his blood were found on a nearby bridge.

The victims’ son, who is a bodybuilder has now confessed to the killing saying that he killed his father after a brief fight and then murdered his mother when she walked in on them arguing.

The argument that led to the murder started when the father asked his son to get out of bed and take the family dog out for a walk.

When he refused, the father and son got involved in an argument. Benno said:

“Dad accused me of being a failure. I just wanted silence. So I shut him up.”

He said he had gone to his room to sleep to avoid a further argument with his father. He complained that his dad woke him up and continued to complain that he was not doing his share of the household chores.

He then decided to strangle him to stop nagging.

He said:

“I took the first climbing rope I found from the plastic tray of my tools. We were in the hallway and we fell together on the ground. I just remember that I squeezed very tightly.”

Benno said that his mum returned home soon after and he strangled her with the same rope.

He said:

“I did it without even saying goodbye.”

The son said that he then threw their bodies off a bridge into the river.

Mr. Benno man is now in prison in Bolzano on charges of murder and body concealment as the investigation continues.
