Texas Felonies
A police officer may arrest upon satisfactory proof from credible person that felony committed and offender about to escape. Under Cornejo v. State, private citizens who witnessed crime and victims are inherently credible. There are four requirements: credible person, not time to prepare warrant, felony, and offender about to escape. The escape requirement is met where the suspect has previously fled or otherwise evidences an intention to flee. Satisfactory proof of escape is not established by the mere fact a suspect travels from one place to another. Officers who reasonably believe that further investigation of an offense may be necessary in order to justify the issuance of a warrant, and where those officers undertake that invest lawfully and w/o impinging upon reasonable expectations of privacy, and where that invest leads to the receipt of info which in combo with their other info constitutes probable cause to arrest the suspect, but that info is obtained in the presence of the suspect under circumstance which would lead the officers reasonably to believe that the suspect would take flight if given the opport to do so, the officers are authorized to arrest the suspect without first obtaining a warrant.
