A 36-year-old man pleaded not guilty today to stabbing his father during an argument in their Azusa home, the Los Angeles County District Attorney's Office announced.

Marlon Enrique Juares (dob 7/16/79) has been charged with two felony counts in case KA112646: attempted murder and making criminal threats.

The felony complaint includes a special allegation that the defendant personally used a deadly and dangerous weapon, a knife, during the commission of the crime. Additionally, the charging document alleges that Juares inflicted great bodily injury on the victim.
