BALTIMORE, Maryland — With no real place to call home, 67-year-old Randolph Cockrell slept on a porch on Oakmont Avenue Tuesday evening."I didn't know whether the person was still living or what?" recalled Tanya Teagle, who saw police standing over a body in her yard across the alley the next morning, and later learned it was the homeless man known in the area as Mr. Randolph, "He was the neighborhood nuisance.  He would mess with everybody, but you just ignored him and go about your way.  Sometimes he joked with you.  Sometimes he argued with you, but he was a fun person.  He didn't really do too much to bother anyone."That is, until somehow he appears to have drawn the ire of 19-year-old Dion Dixon."The suspect, Mr. Dixon, in some way confronted him,” said Interim Baltimore City Police Commissioner Gary Tuggle, “We don't know what the motive was, but he began assaulting him, chased him and ultimately beat him with a brick."About a mile from the crime scene, friends of the victim's family say Randolph's alcoholism landed him on the street."He would drink too much... get a little belligerent, but most of the time, it was because he was drunk... not that he wanted to harm anybody. He wasn't hurtful,” said Krystal Turner.In fact, some say they had seen Randolph and Dixon together in recent days, laughing and hanging out together, which makes it all that much more disturbing that the teen could be capable of beating him to death with a brick."He walked around with a walker so he could barely walk,” said Teagle, “He's not going to do anything to hurt anybody, because he's incapable to me.  It was real sad to hear someone did that to him — somebody that's defenseless you know?"Dixon is being held at Central Booking on a series of charges including murder and assault. 1840

Before kicking off Election Day events, Democratic presidential nominee Joe Biden began his Tuesday with family off the campaign trail.Biden and his wife Jill first attended St. Joseph on the Brandywine in Delaware for a Tuesday morning mass. While there, the couple stopped at son Beau Biden's grave, USA Today reported.Beau died of brain cancer in 2015.After leaving the church, Biden headed off to Pennsylvania, where he joined up with his granddaughters Finnegan and Natalie Biden in Scranton to visit his childhood home.When he arrived at the home, Biden greeted the crowd and said, "It's good to be home!," the Associated Press reported.According to Axios, Biden signed a wall inside the home. 707

BETHESDA, Maryland — The Montgomery County Police press office said Tuesday afternoon that it received a call to assist for a report of an active shooter at Walter Reed National Military Medical Center.Around 3:15 p.m. Eastern, reports indicated it was a drill, not an actual active shooter situation.During the situation, Rep. Dutch Ruppersberger, D-Maryland, tweeted about it from inside the center."I am currently at Walter Reed Medical in Bethesda where we've been told there is an active shooter," Ruppersberger said. "I am currently safe in a conference room w/ approx 40 others."Two individuals separately told CNN they were inside the building at Walter Reed just before 3 p.m. Tuesday and were told to continue to shelter in place. One individual said loudspeakers announced that it was still an active situation. The other individual reported hearing lots of sirens. 884

Being home more during the pandemic, and with less traffic on the roads from stay-at-home orders, many people have heard more bird calls and the sounds of nature in urban areas. Scientists now say at least one bird species has been able to adjust their bird song because of the lack of human noise to compete with.Researchers have been studying the white-crowned sparrows in and around San Francisco for more than two decades. They compare their songs in recent years with recordings made in the 1970s.They found as traffic levels increased over the decades, the lowest frequencies of the sparrows’ song rose. This allowed their song to be heard above the low hum of vehicles. The top frequencies remained the same, so the total frequency bandwidth of their communication was narrowed.Degrading their songs this way, and limiting their range, makes them less effective at deterring rivals, attracting mates, or hearing their own chicks, according to researchers. In noisy environments, birds have to sing louder, which research has shown can result in stress and can speed up a bird’s aging and disrupt their metabolisms.When stay-at-home orders and coronavirus pandemic safety measures were put in place in March, the lead researcher, Elizabeth Derryberry, remembers seeing an image of the Golden Gate Bridge in San Francisco completely empty of cars or humans. She wondered how the sparrows were responding.They compared audio recordings of the bird songs from spring 2015 and 2016, to those taken this spring. The recordings were made in a variety of urban and rural locations around the greater San Francisco area.“We found that birds sung at lower minimum frequencies, achieving greater bandwidth songs in newly open acoustic space. An increase in frequency bandwidth results in the transmission of more information and greater vocal performance,” the study states.The samples taken in 2020 revealed the white-crowned sparrows had changed their tune, so-to-speak, and were singing softer and using a wider range of frequencies. They also were able to communicate twice as far as previous recordings.“This doubling in communication distance could elevate fitness by reducing territorial conflicts and increasing mating potential,” researchers stated.Researchers also say this explains why more people report hearing birds during the pandemic. Since the songs are traveling farther distances, humans are able to hear more of them.They also say the changes in the birds’ songs were more pronounced in urban areas compared to the rural location samples. This would make sense, they say, because the traffic noise did not change as drastically in the rural locations during the pandemic.“Our findings indicate that songbirds like white-crowned sparrows have a striking capacity to exploit newly empty soundscapes following acute but ephemeral amelioration of noise pollution, suggesting that lasting remediation might engender even more promising outcomes, such as demographic recovery and higher species diversity in urban areas,” they concluded. 3055

Bill Gates is sorry that he made it so annoying to log in to your computer.The billionaire Microsoft co-founder admitted Wednesday that the Control-Alt-Delete function used to start up Windows computers is an awkward maneuver."If I could make one small edit, I'd make that a single key," Gates said Wednesday on a panel at the Bloomberg Global Business Forum in New York City.It's a confession Gates has made before. In 2013, he blamed IBM for the issue. 467
