GERONIMO — Comanche County Sheriff Kenny Stradley had assumed Amber Alerts were broadcast nationwide. This week’s search for Aja Johnson has taught the veteran lawman otherwise. "I must admit I thought those Amber Alerts went out across the U.S.,” Stradley said. "Evidently, I was mistaken. That needs to change. When this is all over I will see what I can do about getting that changed. Right now, we need to find that little girl.” Stradley requested the Amber Alert on Sunday night after the body of Aja’s slain mother, Tonya Hobbs, was found in the small town of Geronimo south of Lawton. Hobbs, 37, was found beaten to death inside the recreational vehicle of her estranged husband, Lester Hobbs. The slaying was reported by Lester Hobbs’ sister, Mildred Anderson, at 9:42 p.m., according to a Comanche County court affidavit. County deputies and Oklahoma State Bureau of Investigation agents were called, and it was quickly deduced that 7-year-old Aja, Lester Hobbs and Tonya Hobbs’ white 1992 Toyota Paseo were missing. It was determined the report met Amber Alert guidelines, and an alert was issued at midnight. Based on an interview with Anderson, investigators learned that Lester and Tonya Hobbs and Aja were last seen at 7 p.m. Saturday after having dinner at Anderson’s trailer home on the same town lot as the RV. Investigators realized the alleged abductor may have been on the run for as long as 29 hours. "This is an odd situation in that Lester had a 24- to 29-hour jump on us,” said Jessica Brown, OSBI spokeswoman. "He certainly had enough time to travel far away from Oklahoma, if in fact, that’s what he did. We just don’t know. That’s why a national Amber Alert system is paramount.” Texas, Kansas, Arkansas, Colorado and Louisiana are generally cooperative about issuing Oklahoma’s Amber Alert requests, Brown said. Yet it appears only Texas issued an Amber Alert in Aja’s case, and the Texas alert was canceled on Friday. "I understand the need for national guidelines,” Brown said. "We have guidelines at the state level, and that’s fine. But I don’t see why a national system would be a problem. Only makes sense, right?” In 2003, then-President George W. Bush signed the Prosecutorial Remedies and Other Tools to end the Exploitation of Children Today (PROTECT) Act into law. The act codified the national coordination of state and local Amber Alert programs, but stopped short of establishing a national system. Each state chooses when to release an Amber Alert. Local authorities say they have done everything to maximize resources in the search for Aja. Comanche County District Attorney Fred Smith filed first-degree murder and kidnapping charges against Lester Hobbs last week. He said he did so to use the services of the U.S. Marshal’s Office and the FBI in case if it became a multistate chase. "Now if we have a sighting in, say, Montana, I don’t have to pull one of my guys from down here and send him up there,” Stradley said. "I can call the U.S. Marshal’s regional office up there and get some assistance immediately.” Stradley said he still understands the importance of Amber Alerts, which have proven successful since their creation in 1997. In 2008 — the most recent data available — 194 Amber Alerts were issued nationwide involving 256 children, according to The National Center for Missing and Exploited Children. The center reported that 166 of those cases resulted in recovery; about half could be attributed directly to the issuance of Amber Alerts. Eight of the children were dead when they were found.
