Phoenix police arrest suspect in fatal unprovoked assault that killed 74-year-old Juanito Falcon

Arrest follows investigation into daytime attack near 17th Avenue and Bethany Home Road

Phoenix police have arrested a 41-year-old man in connection with a deadly assault that left a 74-year-old grandfather dead, concluding a weeks-long investigation into an incident described by investigators as unprovoked.

The victim, identified as Juanito Falcon, was attacked on the morning of February 16 while walking near the intersection of 17th Avenue and Bethany Home Road, police said. Officers responding to the area located Falcon with serious head injuries. He was taken to a hospital, where he later died.

What investigators say happened

Detectives determined Falcon was assaulted “for no apparent reason,” based on the initial investigative findings released by police. Court paperwork tied to the case alleges the suspect, Marcus Williams, punched Falcon in the face, causing him to fall and strike his head.

Falcon died two days after the assault, police said, turning the case into a homicide investigation. Police later announced that detectives developed probable cause to arrest Williams.

Police said the victim was attacked while walking in the area and that the assault appeared unprovoked.

Charges and next steps in the case

Authorities have not publicly detailed all charges filed in court, but police characterized the arrest as connected to Falcon’s death. As with all criminal cases, the suspect is presumed innocent unless and until proven guilty in court.

Investigations of fatal assaults typically rely on a combination of witness interviews, medical findings, scene evidence, and any available video. Police have not specified what evidence led to the probable-cause determination in this case, and have not released additional details about a possible motive.
