DALLAS - Police in Dallas said four people were killed and 15 were injured in a series of shootings in a city neighborhood on Halloween night, according to The Guardian's report on the Halloween night shootings.

The Guardian reported that police said three separate shootings occurred in the Deep Ellum neighborhood and that investigators were trying to determine whether they were related. Police Chief Daniel Comeaux said police were still working to determine whether the shootings were connected, the paper reported.

ABC News reported that the three shootings in Deep Ellum "appeared to be unrelated," according to police. The account is ABC News's report on the Dallas shootings, which gave the same totals of four dead and 15 injured.

The two outlets therefore differ on the connection between the shootings. The Guardian reported that police had not yet determined whether the incidents were related, while ABC News reported that police said they appeared to be unrelated. Neither summary available for this report indicates that police have confirmed a link or ruled one out.

The Guardian also reported that the Dallas shootings were among several violent incidents nationwide over the Halloween weekend. The reports reviewed for this story do not describe suspects, arrests, or a motive in the Dallas shootings.
