Las Vegas morning update for Wednesday, Feb. 21

Police have arrested two people in connection with a Monday night robbery at the South Point. Police said a woman walked up to a casino cage at the South Point, showed the cashier a gun and demanded money. Now Jason Lockwood and Tina Lopez, both 37, are booked into the Clark County Detention Center. A Las Vegas man suspected of fatally shooting two homeless men and injuring two other people has been taken into custody. 26-year-old Joshua Emmanuel Castellon faces two counts each of murder and attempted murder in addition to a federal gun charge. A federal complaint says Castellon identified himself as a Lyft driver. Police still do not have a motive for the shootings. A fire that started last night at Clark County Wetlands Park is finally contained. A little more than 14 acres burned. No injuries were reported, and the fire did not threaten any buildings. The cause of the fire is under investigation.
