West Miami police say a 38-year-old man turned a consensual encounter into a violent assault, pulling a gun, choking and beating his sex partner after the partner objected when he allegedly smeared fecal matter during sex. Officers say the victim lost consciousness twice during the attack, suffered cuts and swelling to his face, and ultimately fled to a neighbor’s home for help. Police later found Luis Alberto Negrin inside a West Miami residence, where they say he barricaded himself for about two hours before finally opening the door. He was booked on multiple felony counts.
How police say the attack unfolded
According to an arrest report, West Miami officers were called around 6 a.m. to the 6100 block of Southwest 14th Street, where they found the victim “crying and bleeding in the middle of the roadway.” The man told officers that he and Negrin had been drinking and smoking earlier that morning, which led to sex and then an argument after the alleged fecal-matter act, Local 10 reports. Police say that is when Negrin pulled a small silver firearm, pointed it at the victim’s head and followed him into the kitchen, where the confrontation escalated.
What officers allege happened next
Investigators wrote that the victim said Negrin kept the gun trained on his head while closing in. At that point, according to the report, Negrin allegedly put the man in a headlock, applied extreme pressure to his neck and punched him several times, causing cuts, redness and swelling. The victim told officers he believed Negrin might shoot him and kept looking for a chance to escape. Police say he finally broke free and ran to a neighbor’s house. Negrin also allegedly grabbed the victim’s cellphone to stop him from calling 911 before officers took him into custody, according to Local 10.
Charges and legal context
Police say Negrin was booked on charges of aggravated assault with a firearm, battery by strangulation, tampering with a witness or victim and battery. He was being held at the Turner Guilford Knight Correctional Center on an $8,500 bond. Under Florida law, domestic battery by strangulation is a felony offense that carries significant penalties, as outlined in the Florida Statutes (784.041). The state’s witness-tampering statute can be charged at different felony levels depending on the underlying crime, per the Florida Statutes (914.22). Prosecutors will review the arrest report and evidence before deciding on final charges and any possible enhancements.
Local context and resources
Disturbing details like these are not an isolated shock in the Miami area. In December 2025, a separate report described an alleged break in where a suspect entered a man’s apartment, touched him inappropriately while he slept and then urinated on him, part of a string of unsettling sexual-assault cases in the region, according to CBS Miami.
