The GoFundMe page was set up one day prior, aiming to raise $75,000 (£59,500) for the family of Elizabeth Lopez-Galvan, who died in the shooting that also left 22 people injured, including several children.

"Sending my deepest sympathies and condolences in the wake of your devastating loss. With love, Taylor Swift," read a message next to a $50,000 donation to the cause. A second donation in the same amount was deposited minutes later.

A Swift's aide confirmed to Variety magazine that the donations on the page were in fact the singer's.

Along with Swift, more than 2,000 people have donated to the page, which has raised more than $200,000 (£158,800).

Police said the shooting on Wednesday was the result of a "dispute" and two juveniles were among those detained.

Up to a million jubilant fans had gathered for the parade of NFL champions Wednesday afternoon when shots rang out.

Mass shootings are common in the United States, where there are more guns than people, and about a third of adults own a firearm.

The Chiefs were celebrating their third Super Bowl title in five seasons after beating the San Francisco 49ers in Las Vegas on Sunday.

Swift is dating the tight end of the Chiefs, Travis Kelce, and was a regular presence at games throughout the season including the championship Sunday.

The megastar is currently in Australia as part of her blockbuster Eras world tour.
