FRESNO, Calif. — One person died and four others, including a suspected gunman, were wounded today when he opened fire at a food service company in Fresno, Calif., police said.

The suspect, a parolee who worked at the firm and was identified as Lawrence Jones, shot himself in the head outside the building and was in critical condition, police said.

Two of the wounded victims were in critical condition and the other was in serious condition.

The shooting occurred at the Apple Valley Farms plant in the central part of the city.

Apple Valley Farms is a food service equipment company that 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.”
