The police released blurry security footage of a gray sedan tied to his three killers. His wife, Maria Diaz, has gone on television to plead for help. “I just want answers,” Ms. Diaz said as she sat in her living room, where a memorial poster from his co-workers at the Paris Las Vegas Hotel is still tucked beside the TV. “I want to see them face to face. I want to ask them, was it worth it?” But so far, nothing. Detectives in Las Vegas pride themselves on having one of the country’s better track records for solving homicides, clearing nearly eight in every 10 cases while many other big-city departments struggle to solve half of their murders. But The nation’s murder rate, which has declined sharply for the last 20 years, In Las Vegas, the victims are a mix of African-Americans, whites and Latinos who have been killed during robberies, gang shootings, drug disputes and domestic violence incidents. For homicide detectives here, the most disturbing factor may be that much of the killing is being committed by teenagers and men in their early 20s, many of whom do not understand the consequences of engaging in violence. Recently, a 22-year-old, arrested after a double homicide, asked investigators if he was going to be released so he could start a new job. In another recent shooting, one 15-year-old boy killed another 15-year-old boy amid a barrage of 80 bullets during a gun battle that encompassed three crime scenes. The police are also finding more guns on the street — the percent of homicides killed by guns has increased this year to 72 percent, from 66 percent last year. “You find out there was a minor altercation and someone pulled out a gun,” said Lt. Daniel McGrath, who heads the Police Department’s homicide section. “They are so quick to resort to violence that it goes from profanity to shooting.” As homicides here have swelled to 125 so far this year — a 27 percent increase over 2015 — detectives have watched caseloads grow to five or six apiece, and have become accustomed to phones ringing at 3 a.m. bringing more bad news. “I’ve got a lot of tired people,” Lieutenant McGrath said. The pace of the killings has been relentless, even for veteran detectives, who have seen the number creep steadily upward, from 84 in 2012, and are spending more of their time at crime scenes. April was especially violent, with 24 homicides, the most in any month in the city’s history. While the pace has slowed somewhat, the count this year may surpass the 157 killed in 2006. The city’s worst year was 1996, when 167 people were murdered. The homicide clearance rate for Las Vegas remains a point of satisfaction for investigators even as they are swamped with cases. Last week, the unit added two detectives to bring the total to 21, in order to help with the caseload, Lieutenant McGrath said. And Las Vegas is still far better than most cities at clearing homicides — which generally means that a suspect has been arrested or identified. In Chicago, for instance, detectives solve about 30 percent of their cases, and Philadelphia and Baltimore investigators clear about 50 percent. But clearance rates can swing drastically. Detroit, for instance, solved only about 9 percent of its murders in 2012, but now reports a clearance rate of more than 60 percent. Clearance data, like all crime numbers, are self-reported by police departments, which arrive at them in various ways. For instance, while some agencies include the solving of cold case murders to bolster their annual clearance rates, Las Vegas says it counts only cases solved in the year the crimes were committed. Higher murder rates do not necessarily mean more unsolved cases. Criminal research has shown that resolving a case hinges largely on how quickly officers get to a murder scene, how many detectives work the case, and how motivated investigators are to solve it. When a killing happens in Las Vegas’s more violent neighborhoods, volunteer teams allied with the police head to the scene and to hospitals and funerals to urge people not to answer blood with blood. Weeks later, they knock on doors with community policing units to urge witnesses to come forward and help find the killer. “The root of this problem is poverty and drugs,” said Lekisha Hayes, who runs the But for victims’ families, the math of murder is simple and unforgiving: More deaths across the Police Department’s jurisdiction of about 1.5 million people mean more open cases, more unanswered questions, more fears about killers still uncaught. And more families like the Diazes left in limbo. The Diazes worked at the same casino on the Strip, Maria at cafes and gift shops on the day shift, and Heriberto cleaning casino floors at night. Their opposing shifts meant they spent most days apart, but she would take him a coffee and he would come to her shop and tap on the counter to let her know he was there. He did not care for the Spanish language’s bouquet of affectionate nicknames, so she was surprised when he called her “mija” shortly before he was killed. Ms. Diaz passes the spot where her husband was killed, just seven houses from her front door, each day as she takes her son and daughter to school. She thinks about his last thoughts, and whether she could be doing something to unravel the mystery of his murder. His cellphone was stolen in the attack, she said, and she has kept paying the bills for seven months, just in case someone uses it and provides a potential clue for the police. She said she called the number for the first time last week, but it went straight to voice mail. Ms. Diaz said she and her son and daughter, Eduardo, 17, and Monic , 12, have been unnerved by the gunshots, ambulance sirens and yells of drunks that animate the night around their blue stucco home in northeast Las Vegas, perpetually strung with Christmas lights. Eduardo found a bullet that had pierced the garage door a few months ago. On the other side of town, in Amber Santee’s garden apartment, memorial candles are clustered on the kitchen counter; dried rose petals from her father Mark’s funeral sit in a glass vase; and newspapers mentioning his unsolved April murder are piled on the kitchen table. “This is my life now,” Ms. Santee, 28, said. The night he was killed in April, Mr. Santee, 48, was the lone security guard working a 5-to-11 p.m. shift at a luxury apartment complex being built on the fast-growing west side of Las Vegas. He traded text messages with Ms. Santee, cheering her on as she got ready for chemistry and statistics finals. For years, Mr. Santee had been just shy of an associate degree, and worked a series of hourly security and factory jobs. “Keep on pushing for the gold Am!!!” he wrote at 6:41 p.m. By about 10:30 p.m., Ms. Santee said, he was dead. The police believe Mr. Santee may have been trying to stop a robbery when he was shot several times in the head. In the months after his death, public attention swelled and faded as Ms. Santee agonized over troubling details of his murder. The crosses she planted outside the Elysian apartments to mark his death were torn down recently when rock gardens were put in. But Ms. Santee said she had faith her father’s killers would be caught. “We just have to wait,” she said.
