Boulder police: Bedroom sneak snatched laptop
Mar 6th
Sketch of burglary suspect released; police caution residents about computer thefts
Boulder police are looking for a male suspect who entered a residence in the 1200 block of College Avenue and reportedly stole a laptop computer and jewelry from the residence. A composite sketch of the suspect is attached.
The burglary took place on Sunday, Feb. 26. A female victim told police she awoke to find an unknown male standing in her bedroom. When she asked him what he was doing there, he claimed that one of her roommates had told him he could stay there because he had been drinking. None of the victim’s roommates knew the suspect, who left the residence as the victim was attempting to find out who had allowed him to enter.
The suspect is a black male who is described as:
- In his early 20s
- 5’07” tall
- 160 pounds, medium build
- Clean shaven
- Shaved head
It appears the residence had been left unlocked.
Boulder police are investigating a number of burglaries in which residents have left their homes unlocked. Police remind residents to lock their doors, even if they’re only going to be gone for a little while. It’s also a good idea to keep curtains closed, so that prospective thieves can’t see into the home. There are a number of computer applications available that allow a laptop to be located through a GPS system, and police encourage laptop owners to sign up for or purchase this type of program.
The case number is 12-2647.
Anyone with information is asked to contact Detective Kristin Weisbach at 303-441-4474.Those who have information but wish to remain anonymous may contact the Northern Colorado Crime Stoppers at 1-800-222-TIPS (8477) or 1-800-444-3776.

CU Boulder — LA air pollution has a surprise problem
Mar 2nd
Gasoline worse than diesel when it
comes to some types of air pollution
comes to some types of air pollution
The exhaust fumes from gasoline vehicles contribute more to the production of a specific type of air pollution — secondary organic aerosols — than those from diesel vehicles, according to a new study by scientists from the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences, or CIRES, NOAA’s Earth System Research Laboratory and other colleagues.
“The surprising result we found was that it wasn’t diesel engines that were contributing the most to the organic aerosols in L.A.,” said CIRES research scientist Roya Bahreini who led the study and also works at the National Oceanic and Atmospheric Administration’s ESRL. “This was contrary to what the scientific community expected.”
SOAs are tiny particles that are formed in air and make up typically 40-60 percent of the aerosol mass in urban environments. This is important because fine-particle pollution can cause human health effects, such as heart or respiratory problems.
Due to the harmful nature of these particles and the fact that they can also impact the climate and can reduce visibility, scientists want to understand how they form, Bahreini said. Researchers had already established that SOAs could be formed from gases released by gasoline engines, diesel engines and natural sources — biogenic agents from plants and trees — but they had not determined which of these sources were the most important, she said.
“We needed to do the study in a location where we could separate the contribution from vehicles from that of natural emissions from vegetation,” Bahreini said.
Los Angeles proved to be an ideal location. Flanked by an ocean on one side and by mountains to the north and the east, it is, in terms of air circulation, relatively isolated, Bahreini said. At this location, the scientists made three weekday and three weekend flights with the NOAA P3 research aircraft, which hosted an arsenal of instruments designed to measure different aspects of air pollution.
“Each instrument tells a story about one piece of the puzzle,” Bahreini said. “Where do the particles come from? How are they different from weekday to weekend, and are the sources of vehicle emissions different from weekday to weekend?”
From their measurements, the scientists were able to confirm, as expected, that diesel trucks were used less during weekends, while the use of gasoline vehicles remained nearly constant throughout the week. The team then expected that the weekend levels of SOAs would take a dive from their weekday levels, Bahreini said.
But that was not what they found.
Instead, the levels of SOA particles remained relatively unchanged from their weekday levels. Because the scientists knew that the only two sources for SOA production in this location were gasoline and diesel fumes, the study’s result pointed directly to gasoline as the key source.
“The contribution of diesel to SOA is almost negligible,” Bahreini said. “Even being conservative, we could deduce from our results that the maximum upper limit of contribution to SOA would be 20 percent.”
That leaves gasoline contributing the other 80 percent or more of the SOA, Bahreini said. The finding was published online March 1 in Geophysical Research Letters. “While diesel engines emit other pollutants such as soot and nitrogen oxides, for organic aerosol pollution they are not the primary culprit,” Bahreini said.
If the scientists were to apply their findings from the L.A. study to the rest of the world, a decrease in the emission of organic species from gasoline engines may significantly reduce SOA concentrations on a global scale as well. This suggests future research aimed at understanding ways to reduce gasoline emissions would be valuable.
The study was funded by NOAA’s Climate Change and Air Quality Programs, the California Air Resources Board and the National Science Foundation.
CIRES coauthors on the team include Joost de Gouw, Carsten Warneke, Harald Stark, William Dube, Jessica Gilman, Katherine Hall, John Holloway, Anne Perring, Joshua Schwarz, Ryan Spackman and Nicholas Wagner.
CU expert: Preventing school violence is everybody’s job
Feb 29th
School violence can be prevented,
University of Colorado expert says
University of Colorado expert says
The tragic school shooting that occurred Feb. 27 at a suburban Cleveland high school is another reminder that communities can and must take action to prevent school violence, according to Delbert Elliott, a nationally renowned authority on school safety and juvenile violence at the University of Colorado Boulder.
“A key prevention strategy is good surveillance and good intelligence,” said Elliott, founding director of the CU-Boulder Center for the Study and Prevention of Violence. “We need to enlist our students, our teachers and our adults in the community to help us and ask them to notify the police or the sheriff if they see something unusual or have heard that something is about to happen.”
In 80 percent of the school shootings examined by the U.S. Secret Service, someone knew the event was going to take place, Elliott said. “Nationally, we know right now of a dozen or more events for which we got a tip and were able to intervene early so the planned event actually never took place, which is, I think, our very, very best security.” Some of these plans were on the same level of violence as the 1999 shootings at Columbine High School, he said.
In Colorado, there’s a toll-free Safe2Tell reporting system for students and others to call in anonymous tips about safety concerns, the result of collaboration between the CU-Boulder center and the Colorado Attorney General’s office. All tips are treated seriously, and when combined with other sources of information, often result in some kind of intervention. Since 2004, Safe2Tell has received almost 10,000 calls.
From 2004 through 2010, follow-up data indicate that 83 percent of all Safe2Tell incidents resulted in a positive intervention or action. These tips resulted in 415 formal investigations, 359 counseling referrals, 298 prevention/intervention plans, 324 potential suicide interventions, 312 school disciplinary actions, 74 arrests and 28 prevented school attacks.
“An equally critical key to security is to create a welcoming environment in which all students feel that they’re respected, that the rules are applied uniformly to all students, and students feel safe,” Elliott said. “When students feel that some children can get away with bad behavior and others can’t, and there’s bullying going on, that’s when kids feel like they have to take a weapon to school to protect themselves.”
After Columbine raised awareness of the need to prepare for school crises, school safety has improved nationally, Elliott said. In Colorado, the Legislature changed the law to allow schools, law enforcement and social services agencies to legally share information and every school in the state is now required to have a bullying prevention plan.
Any parent in the state can now go into their child’s school and ask to see what the bullying prevention plan is for that school and make sure that the school is following through with it, he said.
Every school, even those in rural areas, needs an “all-hazards” approach to crises that works for a variety of threats: fires, natural hazards, terrorist attacks, chemical spills, a shooter in the building or a hostage takeover, Elliott said. But most schools haven’t practiced these plans with a full response by police, SWAT, fire, victims’ services, mental health services and ambulances — all coordinated by a single command post.
As the responses to both Columbine and Sept. 11 showed, such drills are important because they reveal communications and other crucial response issues between agencies, he said. Such practices could be held on weekends without students being present, he noted.
Elliott also is concerned when school officials tell him that school safety is a lower priority for them than academic performance, that there is no space in their curriculum for an anti-bullying program.
“These two things should not be in competition with each other,” he said. “If you’ve got a problem with students feeling unsafe at school, you’re not going to improve academic performance because school safety is a necessary precondition for students to be able to concentrate and even to be willing to come to school.
“We argue that being safe at school and improving academic performance go hand in hand.”
Six percent of schoolchildren reported that they had not come to school on occasion because they were afraid of being threatened or assaulted according to the most recent Centers for Disease Control survey, Elliott said.
“Nevertheless, students are more likely to be a victim of violence away from school than at school by a huge margin,” said Elliott, who was the senior scientific editor of the U.S. Surgeon General’s Report on Youth Violence issued in 2001.
