UPDATE: 
 
 12:00 P.M. — A week after a man began his alleged killing spree, investigators say they have one message for him and his accomplice: “Surrender or end up in a cemetery.” 
 
 Santa Rosa County Sheriff Bob Johnson makes the statement from a Tuesday morning press conference to update the public on the search for suspected murderer Billy Boyette Jr. and the woman traveling with him Mary Rice. Injured 28-year-old homeowner Kayla Crocker, whose 2-year-old son was home at the time but did not witness the shooting, was rushed to the hospital and is expected to survive. Authorities confirmed via video surveillance that Boyette and Rice took the stolen vehicle to a Shell gas station only minutes later and ate at a nearby Hardee’s. CRIME TIMELINE 
 
 TUESDAY JAN. 31 — Boyette allegedly kills Alicia Greer, 30, and Jacqueline Moore, 49, at the Emerald Sands Inn in Milton, Florida 
 
 FRIDAY FEB. 3 — Boyette allegedly kills Peggy Broz, 52, at her home in Lillian, Alabama 
 
 MONDAY FEB. 6 — Boyette shoots Kayla Crocker, 28, in a home invasion in Beulah, Florida (Crocker expected to survive) and steals her car 
 
 Boyette is believed to have changed his appearance by shaving his head and his goatee. Sheriff Johnson says it was taken at a Walmart two days after Boyette and Rice allegedly killed 30-year-old Alicia Greer and 49-year-old Jacqueline Moore at a hotel in Milton, but before allegedly killing 52-year-old Peggy Broz at her home in Lillian, Alabama. Investigators tell WRBL sister station WKRG the fugitive Billy Boyette Jr. also shot a fourth woman during a home invasion early Monday morning.
– Florida is facing a "running nightmare" with two people on a killing spree that has so far left three women dead and another in critical condition. William "Billy" Boyette and Mary Craig Rice are wanted in the Jan. 31 murders of 30-year-old Alicia Greer—who was in a relationship with Boyette—and 39-year-old Jacqueline Jeanette Moore at a hotel in Milton. Police believe the suspects then drove to Lillian, Ala., killed 52-year-old Peggy Broz in her front yard, and fled with her vehicle on Friday. In the latest incident, the pair are accused of shooting 28-year-old Kayla Crocker and stealing her vehicle in Pensacola on Monday. Crocker was taken to a hospital in critical condition but is expected to survive, reports the Pensacola News Journal. Authorities say Boyette, 44, and Rice, 38, have managed to elude capture by staying "very mobile." They're believed to have camped in wooded areas; two photos circulated by police show the pair walking in woods with supplies and an apparent handgun, reports WKRG. "What we are experiencing is a running nightmare, quite honestly," a police rep says, noting all victims apart from Greer appear to have been selected at random. Another adds Boyette—accused of stabbing and strangling a girlfriend in 2015—has told "many, many people that he will not be taken alive." Authorities "take those threats and those admonitions very seriously," the rep says. Police say the couple are armed and dangerous and should not be approached.
