The man believed to have fatally shot a Galt police officer was identified Wednesday as Humphrey Kenneth Gascon II, 30, of Galt.
Law enforcement officials said Gascon was not a burglary suspect, as originally thought, and had no criminal record. Although he was currently living in Galt, he had former addresses in Sacramento and Stockton, and police believe he may have been a Norteño gang member.
His record included only minor traffic infractions, but no felony arrests, according to Galt Police Lt. Jim Uptegrove, who added that Gascon could have been arrested Tuesday for carrying a loaded firearm in public.
Although some eye-witnesses questioned whether Gascon suffered a self-inflicted gunshot wound, Uptegrove said police are certain the gunman committed suicide.
"We're sure from the evidence we collected," he said. "We also have witnesses that confirm that."
Police believe Gascon shot and killed Officer Kevin Tonn, 35, after Tonn confronted him Tuesday morning. Gascon then turned the gun on himself, police say.
"In short, Officer Tonn's investigation into a reported burglary made him cross paths with a guy who just happened to be in the area carrying a gun. Unfortunately, this man took extreme measures to try to avoid arrest, which would have likely happened had he been found in possession of the weapon," Sacramento County Sheriff's spokesman Sgt. Jason Ramos said in a written statement Wednesday.
It ended up being a call for a violation of a restraining order, although that was not clear at the time officers were dispatched.
Tonn, 35, was a 3 1/2-year veteran of the Galt Police Department. He was currently a K-9 officer.
A funeral service for Tonn will be held Monday at a Sacramento-area church.
Tuesday's shooting occurred in a field near the Union Pacific Railroad tracks north of F Street when Tonn responded to a burglary call at a residence in the 200 block of 2nd Street, according to investigators.
Tonn arrived and saw a door kicked in, but the suspect had left. However, as officers were interviewing witnesses, they observed a subject, later identified as Gascon, walking along the railroad tracks just north of their location, according to Uptegrove.
Tonn went to contact Gascon to question him about the burglary. Soon after he made contact, a physical struggle ensued, police said. Additional officers observed the struggle and responded to assist.
During the struggle, Gascon reportedly pulled a handgun and fired one round at Tonn, before turning and firing several more shots at a responding officer whose name was not released. Gascon then turned the gun on himself and inflicted a fatal wound, Uptegrove said.
Gascon reportedly shot Tonn with a handgun. He matched the ethnicity and age range given for the suspect in the original dispatch call, according to Ramos.
"Something about him gave Officer Tonn reasonable suspicion to want to talk to him in connection to the incident," he wrote. "Officer Tonn was doing his job well, and he would have been remiss not to follow up by at least investigating/checking this guy out to see if he was the suspect."
Tonn was transported with a head injury to Kaiser Hospital in South Sacramento, where he died hours later.
On Wednesday, Tonn's family spoke to the media through their pastor, Jim Barstow.
"Our hearts are broken and crushed over the loss of our beloved son," he read on behalf of Will and Mary Tonn, the officer's parents.
Barstow, the senior pastor of Centerpoint Community Church in Roseville, said the family has been overwhelmed by community support.
"We are comforted by God," Barstow said, adding that the parents hold no ill-will and wish the best for those involved. They thanked the first responders and Kaiser hospital.
They did not wish to talk directly to the media, but attended the press conference, where they lined the front row of the small chapel.
Uptegrove, who also attended and addressed the media while wearing a black band across his badge, said the department was holding up as best as its members could.
"It's a difficult time. Everyone is taking it hard," he said.
He remembered Tonn as an officer always willing to come into work. In fact, Uptegrove said, he logged more hours on a monthly basis than any of his fellow officers.
"He always did whatever was asked of him," he said.
Also on Wednesday, a community vigil organized by a fellow law enforcement academy graduate was planned in Galt. Tonn graduated from the Sacramento Sheriff's Academy in January 2009 and was hired by Galt in September 2009.
Hundreds gathered around a table filled with candles and photographs of Tonn at Galt Community Park, sharing stories of Tonn's humor and dedication to his job, family and friends.
Lodi Police Officer Ryan LaRue, who was a former roommate of Tonn, laughed as he shared stories about Tonn's love of the reality television shows "The Bachelor" and "The Bachelorette."
"He was the funniest person I ever met," said Madison Miranda, a friend of Tonn. "The realest person I ever met."
Others offered prayers and read poems as the soft candlelight illuminated tear-lined faces.
In the course of their investigation Wednesday, police found the original call began when residents came home to find a door kicked in, and reported a burglary, but later determined the incident was related to a violation of a restraining order, Uptegrove said.
"Police responded to a burglary call and responded in that matter. There was every indication that it was a burglary call," he said, adding that it wasn't determined until later on that it was not a burglary. "Officer Tonn probably wouldn't have contacted (Gascon) had he known it was a restraining order call."
It is not clear whether the suspect in that case has been contacted by police or even whether a crime was committed, since he did not enter the residence or take anything, according to Uptegrove. Uptegrove reiterated that the 911 call was for a burglary since the residents found the front door broken in.
Meanwhile, the Galt Area Chamber of Commerce canceled its annual State of the City event scheduled for today.
"We send our deepest condolences to Officer Tonn's family during this most difficult time," Frank Gayaldo, the chamber's executive director, wrote in an email. "We also want to say 'thank you' to Chief William Bowen and his fabulous officers and support staff for doing all that they can to keep us safe."
Other heartfelt messages from around the country continued to pour in Wednesday, including a statement from Gov. Jerry Brown who in a written statement conveyed his and his wife Anne's condolences, calling Tonn's death "a senseless killing."
