Physical Argument Escalates Into A Stabbing In Chino Hills

By Anthony Saude

On Tuesday, August 22, 2017 at approximately 4:12 pm, Robert Thomas Ramirez was involved in a verbal argument with the victim in the backyard of a residence on the 15000 block of Ethel Street (Lower Los Serranos) in the city of Chino Hills.

There was an argument between two men that quickly escalated into fist fight. While the two were wrestling on the ground, Ramirez drew an unknown sharpened object and began stabbing the victim multiple times.

The victim sustained puncture wounds to his left triceps, both forearms and multiple lacerations to his face and back. The victim was able to call 911 and report that he had been stabbed and needed help said Sergeant Babel of the Chino Hills Police Department.

According to the victim, before Ramirez fled the scene he threatened to kill him. The victim said he feared Ramirez would be back to follow through with his threat. Ramirez fled the scene on a bicycle before the deputies arrived at the scene. The officers quickly began an area search and were rewarded for their efforts approximately one hour after the stabbing took place.

The quick acting efficiency of the Chino Hills Police Multiple Enforcement Team (MET), led them to Ramirez in the parking lot of the Los Serrano’s Country Club. Ramirez fled on foot and the officers had to pursue him on foot through the golf course. Ramirez was apprehended and taken into custody without any further incident.

Ramirez was booked at West Valley Detention Center for Attempted Murder and Criminal Threats. Bail was set  $1,075,000.00 and it has been verified with Sergeant Babel that as of August 24th at 1pm Ramirez is still in custody as of 1 pm. The victims name is being kept confidential for his and his family’s safety at this time. The case is still under current investigation and the district attorney can add charges if it turns up any new evidence.
