The prosecutor's office says Josue Rivera, 40, was killed inside his home in the 2700 block of Tyler Avenue around 4:00 a.m.
Rivera was found in the front bedroom of the home on the second floor with multiple head wounds.
"We heard a lot of screaming, a lot of banging. We weren't certain what was going on. My best instinct was to contact the police," said neighbor Tamara Manning.
Police say Rivera's wife, Maria, was inside the home. She was found physically unharmed, but severely traumatized.
Their son, Lamar, was not at home and, police say, he is the chief suspect in the grizzly killing. Lamar's uncle, Luis, says police are now looking for the young man, who is in his early 20s.
"I don't believe it, that's my nephew, I don't believe it. It's shocking," said Luis Rivera, who also lives in the same home in the quiet section of Cramer Hill. Luis said he went out for food and returned 90 minutes later. He said the father and son had been arguing earlier.
"I came back and saw the police," said Luis Rivera.
