German authorities have opened an investigation after an 81-year-old man allegedly fatally shot a 16-year-old boy over a noise complaint. 

Reports say that Giuseppe Del B., an elderly Italian man, shot Sinan F. at around 7:30 a.m. Wednesday in front of an apartment building in which they lived. He then tried to shoot the boy’s mother and missed before turning the gun on himself. He suffered serious injuries and remains in critical condition.

German outlet Bild identified the suspect and victim, as well as the fact that Guiseppe shot Sinan three times, and T-Online reported that he struck Sinan in the head with one of the shots. 

Alexander Retemeyer, spokesperson for the prosecutor’s office in Osnabruck, said that the victim and suspect "knew each other" and it remains unclear if Guiseppe had a license for the weapon, which he classified as a "small caliber pistol."
