Two more people have died after a worker opened fire at a Fresno chicken plant Tuesday morning, authorities said, including the suspected gunman. 
 
 The Fresno County coroner's office said Tuesday afternoon that the death toll stood at three and included suspect Lawrence Jones, 42. Police described one of the victims as a 32-year-old man who was pronounced dead at the Valley Protein plant; no information was immediately available about the second victim. 
 
 Jones, a "discharged parolee" who had worked at the plant for about 14 months, clocked in to work shortly before 5 a.m. and at about 8:30 "pulled out a handgun and began opening fire" near a cold storage section of the building, Fresno Police Chief Jerry Dyer said. 
 
 Officers found Jones outside the building with an apparent gunshot wound to the head, Dyer said. They also found a 32-year-old woman who had been shot in the lower back. 
 
 Three men were found inside: the 32-year-old who was pronounced dead at the scene, a 34-year-old shot in the head and a 28-year-old shot in the neck. The victims were all taken to a local hospital, along with Jones. 
 
 Dyer said investigators still weren't sure what prompted Jones to open fire, but said a coworker told authorities Jones "did not appear himself when he came in to work." Hours later, Dyer said, he pulled out a gun and started shooting. 

 Police say a parolee who killed two people and wounded two others at a chicken processing plant in California moved methodically between three of the victims, putting a handgun against their head or neck and opening fire.

 Fresno Police Chief Jerry Dyer said the victims did not hear the suspect, 42-year-old Lawrence Jones, on Tuesday because the processing plant was loud and at least some of them had noise protectors. 
 
 The fourth victim, a woman, was shot as she tried to flee the plant. 
 
 Dyer says Jones tried to shoot a fifth person, but he was out of bullets. Police believe he died a short time later of a self-inflicted gunshot wound. 
 
 Dyer also released the victims' identities.

 A parolee who worked at a California chicken processing plant opened fire at the business on Tuesday, killing two people and wounding two others before taking his own life, authorities said. 
 
 Police said they didn't know what prompted the attack by Lawrence Jones, 42, midway through his shift at Apple Valley Farms, although other workers told police he did not appear to be himself when he arrived at the plant for work. 
 
 "It is difficult to say at this point if in fact there was a specific target that Jones was looking for," Police Chief Jerry Dyer said. "There was something that must have provoked this incident, perhaps that occurred today, or maybe was building up to today." 
 
 Jones has an extensive criminal history dating back into the 1990s, Dyer said without elaborating. 
 
 Police said they had Jones' home on lockdown and were searching to see if there were any other victims. 
 
 Jones arrived at work just before 5 a.m. About three-and-a-half hours into his shift, he pulled out a handgun and began firing, Dyer said. 
 
 About 30 employees witnessed the shooting, and there were a total of 62 people at work when the gunfire started, police said. 
 
 "We have a lot of work ahead of us. We have at least 30 witnesses that we need to interview," Dyer said. 
 
 Officers found Jones with a gunshot wound to the head and a 32-year-old woman bleeding from a wound to her lower back outside the business. She was in stable condition, Dyer said. 
 
 Three other people were found shot inside. One was pronounced dead at the scene. Jones and another victim were pronounced dead later. 
 
 The company was established in 2005, according to online business records. A call to the company went to a voicemail recording that said "due to an emergency we are closed for the day." 
 
 A woman who answered the phone at a listing for CEO Durbin Breckenridge and identified herself as his wife said she would pass a phone message to him. 
 
 News media and onlookers were kept several blocks from the plant, as police used yellow tape to block access. Dozens of officers swarmed the area. 
 
 Joe Martinez, 45, told the Fresno Bee that he was in the drive-thru lane of a fast-food restaurant when he heard a loud pop that he initially thought was a car backfiring. 
 
 Then he looked to the north and saw a man on the ground with two people standing over him. 
 
 "It's the last thing you expect to see," Martinez said. "It's very upsetting."

– A "discharged parolee" opened fire at a Fresno chicken plant today, killing two people and wounding two more before fatally shooting himself, the Los Angeles Times reports. The suspect was identified as Lawrence Jones, 42; he had worked at the Valley Protein plant for 14 months. Jones reportedly showed up for work just before 5am; police say he "pulled out a handgun and began opening fire" around 8:30am, moving methodically between three of the victims, putting a handgun against their head or neck and opening fire, reports the AP. Two of the three men shot inside the processing plant have died; they did not hear Jones approach because of the plant's noise level, and may have been wearing noise protectors as well, police explained. A fourth victim, a woman, was shot as she tried to flee the plant. Jones apparently tried to shoot a fifth person, but he was out of bullets. He reportedly died a short time later of a self-inflicted gunshot wound. About 30 employees witnessed the shootings.
