Authorities are expanding their statewide manhunt for the now ex-Sacramento Cal Fire battalion chief believed to have killed his girlfriend. 

Authorities say 55-year-old Orville Fleming has ties to the Santa Cruz Mountains and the Sierras, so Cal Fire officials are in the process of securing facilities Fleming could access using his department issued keys.  

Those keys could give let him hide in any of the more than 400 state facilities or travel down private roads and trails.

News10 is reporting that Fleming texted his estranged wife and might have tried to blame her for his girlfriend's killing.  

Meagan Fleming says his text to her read,"Can we put us and our family back together!?"  

She replied, "No!!! It's over sorry!!"

His reported response: "Come and pick me up... We're supposed to grow old together."  

A couple of hours after the time of the alleged murder, Fleming is said to have sent his estranged wife a text reading, "You should have came and picked me up" tagged with frowning face.
