Seven Manteca detectives followed leads throughout the day Friday investigating the shooting death of 31-year-old Antonio “Tony” Duenas in the 100 block of Stockton Avenue at about 11:15 p.m. Thursday.

Three of the investigators were from the Street Crimes Unit and the other four from the detective unit within the police department.  Public information officer Jason Hensley said the team of officers served multiple search warrants during the course of the day and turned up some possible leads.

Police recovered a gun at the scene.

Numerous rounds of gunfire were heard at the time of the shooting by residents and patrolman Richard Smigelski who was driving through the area at the time of the assault.  The officer located two individuals in their early 20s running from an alley as other units from swing and graveyard shifts were rushing to the neighborhood of Stockton and Vine streets near Baccilieri Park in south central Manteca.

Officers set up a perimeter cordoning off several blocks in search of a third individual who had been seen running from the area of the crime scene.  With the help of a citizen, officers were able to detain a third person of interest.  Officers had gone door-to-door in their search. 

Following questioning by detectives it was determined there was insufficient evidence to link the three with the shooting, police said.

Police administered CPR on the shooting victim until medics arrived.  The man was transported by ambulance to Doctors Hospital Medical Center trauma unit in Modesto where he was pronounced dead.

Duenas had been reportedly shot in the upper torso, according to police.

Officers declined to comment as to whether the shooting involved gang members.

A resident in the area of the shooting said he was tired of the street violence.

“Last night there was a shooting in which a young father, fed up with threats and constant bullying took the matter into his own hands and lost,” said the neighbor, who asked not to be identified.

He added that this is all about neighbors who want peace and to have their kids grow up to enjoy life.

“I myself am fed up with this and taking action against them.  How many more lives of good friendly people have to die for something to happen?” he asked.

It was Manteca’s second homicide of the year.
