A Miami-Dade shooting arrest has been made in connection with a deadly incident that authorities say was fueled by jealousy over a relationship. William Serrano Domenech, a 49-year-old homeless man, was taken into custody on Tuesday, August 18, 2026, just one day after the fatal shooting occurred near Northwest 38th Street and Northwest 33rd Avenue in the northwest Miami-Dade area.
The Miami-Dade shooting arrest comes after investigators pieced together a troubling sequence of events that began with what appeared to be a routine social interaction. According to officials, the situation quickly escalated into violence, leaving one man dead and a community shaken by the senseless tragedy.
What Happened During the Northwest Miami-Dade Shooting
According to the arrest report, Serrano Domenech arrived at the location near Northwest 38th Street at approximately 5:35 p.m. on Monday, August 17, 2026. He was reportedly socializing with a witness at the scene when the victim arrived shortly thereafter.
What began as a verbal dispute quickly turned physical. Investigators report that Serrano Domenech started slapping and punching the victim. When the witness attempted to intervene and stop the altercation, the suspect allegedly pulled a handgun from a fanny pack and shot the victim in the abdomen.
Following the shooting, Serrano Domenech fled the scene, heading eastbound on Northwest 38th Street. Emergency responders transported the victim to the Ryder Trauma Center at Jackson Memorial Hospital, where he later succumbed to his injuries. Authorities have not released the victim’s identity at this time.
Jealousy Over Relationship Cited as Motive
Investigators have determined that the Miami-Dade shooting arrest stems from an ongoing dispute between the suspect and the victim. According to the arrest report, Serrano Domenech allegedly harbored jealousy regarding the victim’s relationship with the witness present at the scene.
The witness provided crucial testimony to investigators, stating that the victim was unarmed and did not initiate the physical altercation. This account painted a clear picture of unprovoked aggression that ultimately resulted in a fatal shooting.
The jealousy-fueled dispute appears to have been brewing for some time before it erupted into deadly violence on that Monday evening. The exact nature and duration of the conflict between the two men remains under investigation by Miami-Dade County authorities.
How Deputies Captured the Suspect
The apprehension of Serrano Domenech occurred on Tuesday near Northwest 32nd Street and Northwest 31st Avenue, not far from where the shooting took place. Deputies spotted the suspect in the area and moved to approach him.

“I’m Willy, the guy you’re looking for from yesterday.”
While attempting to retrieve his identification, deputies discovered a handgun inside a bag in Serrano Domenech’s possession. This discovery added additional charges to the case, given the suspect’s criminal history.
Suspect’s Criminal History and Charges Filed
