Better crime labs help meet demand for analysis

I’m a lit­tle con­fused by the arti­cle. Just recently we heard that the Arizona State DPS crime lab was in dire need of fund­ing, so there were going to have to charge local agen­cies money for basic foren­sic ser­vices. Now they are hir­ing 11 new DNA analysts?

It’s great that Mesa got their new lab. They really needed it.

Steve Garrett from Scottsdale is spot on. Officers (and pros­e­cu­tors espe­cially) are ask­ing for more foren­sic analy­sis on a greater num­ber and type of cases.

Mesa Police Chief George Gascón is exag­ger­at­ing a lit­tle I hope. We as tax pay­ers do not need to be foot­ing the bill for DNA analy­sis on every case. Imagine hav­ing to do DNA analy­sis on every crack-pipe and mar­i­juana joint seized in searches.

I don’t know how badly Chandler really needs another lab so soon. They have a rel­a­tively new one cur­rently. Granted they are grow­ing in size, but they have about 6 in house crim­i­nal­ists in the space that Phoenix PD used to have about 18 peo­ple work­ing in.

Also they are crim­i­nal­ists, not crim­i­nol­o­gists. When reporters don’t even know the right word for the type of job they are writ­ing about, it kind of makes one doubt the reli­a­bil­ity of the entire article.

Valley crime labs are grow­ing to keep pace with the ever-increasing demand for foren­sic evidence.

Mesa opens a state-of-the art lab next month, Chandler is plan­ning a new one, Phoenix opened a new lab in June 2007, and Scottsdale plans to open a new lab next September.

“Success breeds more work,” said Todd Griffith, scientific-analysis super­in­ten­dent for the state Department of Public Safety. “There’s more we can do with the evidence.”

He said 11 new tech­ni­cians recently fin­ished train­ing at the DPS lab and the addi­tional per­son­nel would help cut into a back­log of DNA cases.

Steve Garrett, Scottsdale’s forensic-services divi­sion man­ager, said detec­tives used to be more selec­tive by request­ing analy­sis for only major vio­lent crimes such as homi­cides and sex­ual assaults.

But now foren­sic work is per­formed on more rou­tine crimes that affect more peo­ple, such as bur­glar­ies and auto thefts.

“Even though crime goes down, our work goes up,” Garrett said. “They’re giv­ing us more evidence.”

Mesa Police Chief George Gascón said DNA should be used to solve all crimes.

“It’s a tool we’d be silly not to use on every pos­si­ble level,” he said. “Sometimes, peo­ple who com­mit vio­lent crimes com­mit prop­erty crimes. Sometimes, prop­erty crimes lead to vio­lent crimes.”

Mesa started mov­ing into a new $22 mil­lion, 46,000-square-foot lab last week.

Instead of con­duct­ing bal­lis­tics tests in a con­verted closet in the base­ment of Mesa’s munic­i­pal cour­t­house, tech­ni­cians can use the new facility’s bul­let recov­ery tank. A fir­ing range sits next door with cases to store sam­ple guns of var­i­ous types and models.

Criminologists won’t have to wait in line to per­form tests at the new facil­ity, said Deb Rector, Mesa’s forensic-services director.

“It will help get the infor­ma­tion out to detec­tives as quickly as pos­si­ble, to get these peo­ple off the streets as quickly as pos­si­ble,” she said.

Mesa res­i­dents will get a rare glimpse at the work­ings of their new crime lab at a grand open­ing Oct. 23.

The lab plans to assem­ble a crime scene com­plete with guns and bul­let cas­ings out­side the build­ing then show res­i­dents how they would ana­lyze evidence.

“That’s what foren­sics does,” Mesa Commander Bill Peters said. “It allows you to re-enact the crime.”

Mesa police are will­ing to help other cities with DNA analy­sis on a case-by-case basis, but Mesa cases take pri­or­ity, Peters said.

Mesa’s crime lab helped Tempe police make an arrest in the July 20 sex­ual assault of a 73-year-old woman, match­ing DNA found at the scene to sus­pect Graham Buzzi Gravely in about 30 hours, Peters said.

Gravely, 51, sub­se­quently con­fessed to the killing of Linda Dorsey, 28, in Yuma. Her body was found in a canal July 10, 1998.

“We were able to get a match,” Rector said. “We were able to get the name of the individual.”

When crime-lab sci­en­tists get a match, “peo­ple are excited,” she said. “The indi­vid­ual who did the analy­sis, you think, ‘That could have been my grandmother.’ ”

Gascón, who puts a pre­mium on regional coöper­a­tion, said, “If there’s a major crime occur­ring in a neigh­bor­ing city, we’re going to help.” Even when cities have their own labs, they often refer spe­cial­ized test­ing to the DPS lab in Phoenix, Griffith said.

Mesa, for instance, refers blood-toxicology test­ing to DPS to learn what drugs were in a suspect’s system.

Rector said Mesa hoped to start per­form­ing those tests about a year after the new lab opens.

Phoenix refers trace evi­dence tests to DPS, which might include analy­sis of paint smears from a victim’s clothes in a hit-and-run traf­fic fatal­ity, Griffith said.

Cases that require such test­ing are infre­quent and the cost of equip­ment is high, so it isn’t con­sid­ered cost effec­tive to dupli­cate test­ing capa­bil­i­ties, Griffith said.

Griffith said he under­stood why a city the size of Mesa, with about 450,000 res­i­dents, would oper­ate its own crime lab. But he also said it didn’t make sense for many smaller cities because of the expense.

Rita Dyas, Chandler’s forensic-services man­ager, said she appre­ci­ated the DPS lab’s assis­tance on big cases. For instance, the DPS lab ana­lyzed 400 DNA sam­ples before it obtained a match in January to “Chandler Rapist” sus­pect Santana Batiz Aceves.

But “because of the back­logs, we know they can’t do every­thing we’d like,” she said. “It’s first come, first served unless you have a high priority.”

Chandler is work­ing on a five-year plan to build a full-service lab, Dyas said. The present lab is run­ning out of room and per­forms blood-alcohol test­ing, drug analy­sis and latent fin­ger­print analy­sis, Dyas said.
