Separate shootings over the Halloween weekend, many in nightlife districts, left at least six people dead and dozens wounded in several U.S. cities, officials said, according to the Associated Press^1,5.

Dallas recorded the highest toll in that roundup, with police saying four people were killed and 15 others injured in Deep Ellum, a music and restaurant district^1,2,4.

Dallas Police Chief Daniel Comeaux said three shootings unfolded over about an hour and 15 minutes Saturday night into Sunday, and that it was not immediately known why they started^1,2.

ABC News reported the first near the 2600 block of Elm Street about 12:20 a.m., then the 2600 block of Main Street about 1:05 a.m., then the 200 block of S. Crowdus Street about 1:35 a.m.².

Comeaux said detectives were still trying to determine whether the scenes were connected^1,2. ABC News quoted him as saying they had no information that they were related but were still investigating².

Comeaux said some arrests were made without specifying counts or charges, the AP reported¹. ABC News said a suspect was in custody and at least one other was being sought².

The department had increased police presence in the district before the shootings, and no officers were injured, the AP reported¹. Mayor Eric Johnson said public safety must remain the city's top priority so Deep Ellum can be a safe gathering place².

Families told KVUE that Kanisea Scott, 21, and Quincy McCleary were among the four killed; police had not released names³.

In Birmingham, Alabama, Mayor Randall Woodfin said one person was killed and eight others were wounded in two shootings just outside Legion Field after Saturday night's Magic City Classic football game^1,5. Fire officials said two people were in critical condition Sunday¹. Birmingham police said one person was detained and multiple weapons were found¹.

Newark, Delaware, police said six people were shot late Saturday near the University of Delaware campus and taken to hospitals; conditions were not available^1,5. The AP said a shooting early Sunday in Bloomington, Illinois, left a 19-year-old woman dead¹. Police in Fayetteville, Arkansas, also reported nightlife-district shootings, according to the same roundup^1,5.

The New York Times headline put nationwide Halloween shooting deaths and injuries far higher than the AP tally; that article's body was not independently verified here⁶. Investigations in Dallas and other cities were continuing^1,2,4.
