Read the statement of probable clause with the transcript of the killer’s statement. He says he shot the male as he came down the basement stairs and then finished him off in and placed the body on a tarp and dragged it to his workshop and then sat down in his chair.
A few minutes later, the girl comes down the same steps and he shoots her, yada yada.
He’s lying, straight up. Say these two cousins are larking about or burglarizing and he shoots the first, does the second wait long enough for him to get a tarp and move the first body before also descending the same stairs after hearing gunshots. Or calling out for the cousin who disappeared down the stairs and didn’t come back.
No freaking way. Whatever happened, the shooter’s story is bull scat.
He first wounded both of them below the waist, and then later shot them in the face, close up and personal, he even moved the girl before finishing her off face to face.
I think that we can figure that he was talking to them as he was killing them.
