Four grizzly bears captured in western Canada were responsible for the deaths of a mother and her adult daughter earlier this month, Canadian wildlife officials said, according to ABC News. The network reported that investigators believe the killings were a "rare predatory attack." ABC News published its report on November 10.

DNA tests linked four bears to the deaths, officials said, according to CBS News, which identified the victims as Jenny Balcarras and her daughter, Selah Reed. CBS News reported that all four bears were killed to protect the public. CBS News published its report on November 11.

The two reports differ on the fate of the animals. ABC News described the four bears as having been captured, while CBS News said they were killed. Neither ABC News nor CBS News explained whether the capture and the killing were separate actions, or which occurred first.

The reports also differ in the details they give about the victims. CBS News named the mother and daughter, while ABC News described the daughter as an adult and did not name either victim in its summary.

ABC News placed the bears in western Canada and used the phrase "earlier this month" to describe the attack, but neither outlet provided a specific community, the name of the agency leading the investigation, or an exact date for the attack. Neither outlet described how the DNA testing was conducted or when the results were returned.

This account is limited to what the headlines and summaries of the two reports state, and it does not add facts from other sources.
