A Florida man is facing murder charges after deputies say he killed his 16-year-old son with a saw.

Police in central Florida tried early Wednesday to arrest a man suspected of fatally shooting a 40-year-old woman and her three children, ages 21, 17 and 11.

Cal-Maine is a public company and is the largest producer and marketer of shell eggs in the U.S., ARM officials stated in a news release. The company sells its eggs to numerous retailers around the country, including Walmart and Publix. ARM officials said an undercover investigator, who is a retired U.S. Army serviceman, captured surveillance footage of battery-caged hens over a two-month period. Some small cages contained up to 10 birds and "walls of cockroaches" were spotted within the cages, officials said. The undercover investigator said he witnessed the hens being tortured by being kicked, punched, thrown and slammed on the ground.
