Uncertainty around the U.S.-China trade war and a global economic slowdown have caused interest rates to tumble and weighed on the major stock averages in recent weeks. Last month’s jobs report showed a strong consumer, but business investment is low as investors and business owners juggle new tariffs and fiscal policy uncertainty.

Video obtained by The Post shows William Rivas, 39, laying on top of his bleeding estranged wife, 35-year-old Carmen Iris Santiago, after stabbing her repeatedly around 7 p.m. Wednesday inside the Jackson Heights shop.

“We tried to get him off of her but his strength was greater than ours,” explained Tu S’tilo Salon SPA owner Lourdes Salazar, through tears. “And then he tried stabbing us.”

The footage later shows plainclothes police officers arriving at the scene and pulling Rivas away from his dying wife as bystanders look on, some even videotaping the tragic aftermath.
