In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Gangsters Nat Burdell and Brad Conley (Ewing Miles Brown) kidnap wealthy socialite Margaret Chaffee and, joined by gun moll Esther Malone, head for the San Gabriel Mountains to await the ransom they've demanded from Chaffee's father. That night, geologist Dick Cutler sees what he thinks is a meteor crash into the forest. But he doesn't see that out of the smoke from the impact emerges a beautiful glowing blonde female extraterrestrial in a skintight leotard who can kill by touch.
The gangsters hole up at Cutler's cabin. When the alien peeks through a window, Burdell orders Conley to go after her, but the alien kills Conley, his gunshots having no effect on her whatsoever. Burdell then goes out and runs into the alien himself. Although his gunshots are also ineffective, the alien walks away backwards, allowing Burdell to retrieve Conley's body. Back at the cabin, Cutler says that Conley died of "radium poisoning" and that by carrying his body, Burdell has taken a potentially lethal dose of radium and needs to get to a doctor before he dies.
Burdell decides they should flee that night, even though they'll have to navigate a dangerous mountain road in Cutler's headlight-less Jeep. But before they can leave, the alien smashes through the cabin's window. Everyone runs outside. The alien catches Malone and kills her. When the alien tries to grab Burdell, he quickly sidesteps and she tumbles down an embankment. Burdell wrongly thinks she's dead. Cutler and Chaffee have already run back to the cabin. Burdell demands that they leave at once. But as they drive off, the extraterrestrial stops them and kills Burdell.
What are the full names of the gangsters who are holed up at Cutler's cabin?
