October 1– Concertgoers dive over a fence to take cover from gunfire after shots rang out at a country music festival on the Las Vegas Strip. At least 58 people were killed and almost 500 were injured when a gunman opened fire on the crowd.…

LAS VEGAS - Investigators have still not discovered what motivated Stephen Paddock to embark on the worst mass shooting in modern U.S. history but determined that he researched SWAT tactics ahead of the massacre and investigated other possible targets, including the famed California beach in Santa Monica, officials said Friday.

They also determined that Paddock acted alone when he opened fire from his high-rise hotel suite, killing 58 people and injuring hundreds, Clark County Sheriff Joe Lombardo told reporters.

Lombardo made public a preliminary report into the shooting and said he does not expect charges to be filed against Paddock's girlfriend, Marilou Danley, who had been previously called a person of interest in the case. Investigators also found that Paddock had possessed child pornography, Lombardo said.

Paddock's online searches before the shooting included research into SWAT tactics and for other potential public venue targets — and he took photographs of some potential sites, the sheriff said. The searches also included the number of attendees at other concerts in Las Vegas and how many people go to Santa Monica's beach.

The sheriff and the FBI have said they found no link to international terrorism. They said they believe Paddock meticulously prepared and concealed his plan to fire assault-style weapons from the 32nd floor of the Mandalay Bay hotel into a crowd of 22,000 people attending the Route 91 Harvest Festival music below.

Paddock fired more than 1,100 bullets, mostly from two windows in the high-rise hotel, Lombardo has said. That includes about 200 shots fired through Paddock's hotel room door into a hallway where an unarmed hotel security guard was wounded in the leg and a maintenance engineer took cover to avoid being hit.

Several bullets hit aviation fuel storage tanks at nearby McCarran International Airport that did not explode. Authorities reported finding about 4,000 unused bullets in Paddock's two-room suite, including incendiary rounds that Lombardo said were not used.

Investigators found 23 guns in the rooms, including 12 rifles that a federal Bureau of Alcohol, Tobacco and Firearms official said were fitted with "bump stock" devices that allowed rapid-fire shooting similar to fully automatic operation.

Paddock killed himself with a gunshot to the mouth before police reached him. The 64-year-old retired accountant and multimillionaire real estate investor had earned hotel upgrades as a high-stakes video poker gambler at several Las Vegas casino resorts.

Danley was in the Philippines at the time of the shooting.

Lombardo and Aaron Rouse, FBI agent in charge in Las Vegas, had described Danley as a person of interest in the investigation but not a suspect. She was questioned by the FBI when she arrived in Los Angeles from overseas, and was described as cooperating with investigators.

However, a document filed Oct. 6 and unsealed last Friday by a federal judge in Las Vegas said the FBI considered Danley "the most likely person who aided or abetted Stephen Paddock."

Questions have been raised about Danley's receipt in the Philippines of a $10,000 wire transfer from Paddock just days before the shooting.

FBI warrant documents also showed that Danley told investigators that they would find her fingerprints on bullets used during the attack because she would sometimes help Paddock load high-volume ammunition magazines, and that Danley deleted her Facebook account in the hours immediately following the shooting.

The Clark County coroner ruled that all 58 people killed in the attack died of gunshot wounds. Paddock's death was ruled a suicide. Media organizations including The Associated Press are seeking autopsy records that have not been made public.

Paddock's body was cremated and his brother Eric Paddock, who lives in Orlando, flew to Las Vegas to retrieve them after the coroner would not ship the ashes to Florida.

Eric Paddock told the Review-Journal he intends to put the ashes in a safe deposit box.
