San Francisco police say investigators are working "tirelessly" to make an arrest after Cash App Founder Bob Lee died after pleading with 911 for help.
Lee died early Tuesday morning at around 2:30 a.m. in Rincon Hill, which is a neighborhood on the edge of the San Francisco Bay, according to police.
"We would like to express our deepest condolences to the family, friends and loved ones of Mr. Lee. There is no place for this kind of violent crime against anyone in our city," San Francisco Police Public Information Officer Adam Lobsinger said in a video update Thursday.
"We want to assure everyone that our investigators are working tirelessly to make an arrest and bring justice to Mr. Lee and his loved ones, just as we tried to do in every homicide that occurs in our city."

Lee moved out of San Francisco to Miami last fall because of safety concerns and was recently on a trip to San Francisco.
Prior to leaving Silicon Valley, Lee addressed the increasing rise in hate crime against Asians.
"We need to make examples of the perpetrators: prosecute them as hate crimes to the full extent of the law," he tweeted.
