Names in news activity to report this week.

Concetta Callahan is due to arrive in Tucson next week as co-anchor of KMSB 11’s “Daybreak” from 7-9 a.m. weekdays. Callahan also will report during the 4:30-7 a.m. news on KOLD 13, as part of the two stations’ shared services agreement. She fills the vacancy created when Gina Trunzo left in May for medical reasons. Callahan comes to Tucson from Rock Island, Ill., where she was the weekend news anchor for CBS serving the Quad Cities market of Rock Island and Moline, Ill., and Davenport and Bettendorf, Iowa, A native of Houston, she also worked in Laredo, Texas.

Also on the morning news front, Steve Nuñez is out after just one year as co-anchor of KGUN 9’s “Good Morning Tucson.” And he’s gone from the station. Nuñez couldn’t be reached for comment and station officials weren’t talking other than to confirm the parting of ways. News Director Forrest Carr told the trade publication TV Spy, “We wish him the very best of luck.” The word from staffers is that station officials wanted to reassign Nuñez to a reporter position with no change in pay. But after he took to Facebook — saying among other things, “I gave it My BEST. And, while it wasn’t good enough for our viewers, it was GOOD enough for ME, Camila and my family! I lost my job” — he was told the reassignment offer was no longer on the table and he was out.

Peter Michaels, who was news director and executive producer for Arizona Public Media the past 8½ years, is the new communications director for the National Institute for Civil Discourse. It makes for a completed circle for Michaels. The institute, which is part of the University of Arizona, was formed in the aftermath of the Jan. 8, 2011 shootings at a constituent event being held by then U.S. Rep. Gabrielle Giffords that left six people and 13 others, including Giffords, injured. Through happenstances, Michaels’ wife was at the shopping center where the shootings took place and as a result, his reports on NPR were among the first national accounts of the event. Michaels’ career of more than 30 years included stops at NPR in Washington, D.C., and NBC in New York prior to coming to Tucson.

Another departure from Arizona Public Media, Wendy Erica Werden is the new director of community outreach for U.S. Rep. Ron Barber’s office. It’s the job Gabe Zimmermann had with Giffords’ before he was killed in the Jan. 8 shooting. Werden had director of marketing and brand management for Arizona Public Media for about 4½ years.

Political debates

Ron Barber and Martha McSally will appear before a panel of reporters in a live forum at 6 p.m. Oct. 23 that will be broadcast live on KUAT-TV 6, KUAZ 89.1-FM and online at www.azpm.org. The one-hour forum will take place in the Grand Ballroom of the Student Union Memorial Center on the University of Arizona campus.

The media panelists will be reporters Christopher Conover and Andrea Kelly from Arizona Public Media, Jim Nintzel from the Tucson Weekly and Katy Murray, president of the Associated Students of UA, which is hosting the event.

It is one of only two public debate situations for the Congressional District 2 candidates. Next week, Barber, a Democrat, and McSally, a Republican, are scheduled to appear in a debate at 6 p.m. Oct. 17 at Buena High School Performing Arts Center in Sierra Vista.

Meanwhile, the candidates in Congressional District 2, which extends from the northernmost portion of Pima County through the White Mountains up to Flagstaff, will appear in another forum to be broadcast at 6 p.m. Oct. 24 on Arizona Public Media’s TV, radio and online outlets.

Loose ends tied

It appears Google has fixed its algorithm for news searches on the word “Tucson” so that Tucson News Now aren’t the only results. In fact, in a search on Wednesday this week the newsroom for KOLD 13 and KMSB 11 wasn’t the source of a single news story on one of the first 10 pages. Despite that, the search still doesn’t necessarily produce news of or about Tucson, which is presumably what one would want with that as a key word. Page 1 of the results included only Tucson-based news stories but there in the middle of page 2 were stories about Jerry Sandusky, the former Penn State football coach being sentenced, and Lady Gaga thowing up on stage, both of which were reported by Tucson news media but have nothing to do with Tucson.

You might recall Alex Miranda, former co-host of KGUN 9’s “The Morning Blend,” was the host of a CBS network reality relationship show called “3” that premiered in July but didn’t even last as long as the show’s title. If per chance those two episodes had you hooked, CBS has made the rest available as an “online exclusive” at www.cbs.com/shows/3/.
