Witness statements is evidence. CC confessed she drove the jeep, but claimed BD is the one who paid her to do so. Jeep owner said he loaned the Jeep to BD. I fail to see why that is not enough to arrest her. Seem to be enough in other cases to hold someone on statement from witness, such as Bella Bond case.
It certainly seems so. I also am a Dallas resident, and it seems on the surface that a mistake was made in letting her go. My understanding is even if they were holding her for outstanding tickets in Plano (Collin County) they could have held her for up to 10 days until Collin county picked her up or declined. Timeline indicates she was released after media reported her connection to the case. I'm not sure what other evidence they would have now to issue a warrant that they did not have on 9/5.... But, maybe they do.
