Earlier quoted context omitted.
That's a common tactic to try and get a suspect to turn themselves in. Sometimes it works. (Most suspects turn themselves in for crimes they've committed. It's actually the exception when police need to go out to arrest a criminal suspect.)
That's when the suspect's identity is known, and the suspect would rather face a bail hearing then try to keep hiding.
For violent offenses, and especially for high-profile murder cases, they don't give the suspect the option of turning themselves in.
