AMES, Iowa -- The driver of a stolen truck who was shot and killed on the Iowa State University campus Monday has been identified as 19-year-old Tyler Comstock of Boone. 
 
 
 
 Ames police also have identified the officer who reportedly fired the shots that killed Comstock following a vehicle pursuit through town as Adam McPherson. McPherson has been with the Ames Police Department for more than eight years and is assigned to the day shift patrol division. 
 
 
 
 Monday’s shooting was the first time McPherson has fired his weapon at a suspect on duty, said Ames police Cmdr. Geoff Huff. McPherson is on paid administrative leave pending an investigation into what occurred and whether he should be charged in the fatal shooting. 
 
 
 
 Huff said Ames police, the Iowa State University police and the Iowa Division of Criminal Investigation are working together on the case. The DCI will lead the investigation into whether McPherson should be charged, and the Story County Attorney’s Office will make the final decision, Huff said. 
 
 
 
 The incident began at 10:17 a.m. Monday when Ames police received a report of a stolen vehicle from a man who said his son had become upset and taken his pickup truck and trailer, according to a news release. McPherson responded, according to Huff, and located the truck at Grand Avenue and South 4th Street. 
 
 
 
 McPherson reportedly followed the vehicle initially before activating his emergency lights. But, instead of pulling over, Comstock is accused of speeding up and continuing west to Beach Avenue. Comstock, at one point, is accused of stopping the vehicle and reversing, pushing the trailer into the police car and partially onto its hood, according to police. 
 
 
 
 Comstock then sped away again, police reported, running a red light and becoming unhitched from the trailer. McPherson continued to follow the truck around Union Drive and eventually north on Morrill Road – against one-way traffic in the bike and pedestrian lanes, according to police. 
 
 
 
 Witnesses told police that people were jumping out of the way of the truck, which then jumped the curb onto a grassy area north of the university’s Campanile. McPherson unsuccessfully tried to ram the vehicle to get it to stop, police reported. 
 
 
 
 Comstock is accused of continuing to drive around the grassy area, prompting pedestrians to jump out of the way, according to Ames police. He eventually stopped in a wooded area but continued to rev the engine and go back and forth, police reported. 
 
 
 
 Officers gave verbal commands to turn off the vehicle, but Comstock didn’t comply, and McPherson is accused of firing six rounds at the truck “to stop the ongoing threat to the public and the officers,” according to police. 
 
 
 
 The truck, while continuing to rev, no longer was moving, and officers approached the vehicle. They found Comstock had been hit by the gunfire, and he was taken to Mary Greeley Medical Center, where he was pronounced dead. 
 
 
 
 Huff told The Gazette on Tuesday that Comstock had threatened police by ramming cars and that it “was a pretty scary situation.” He said the incident happened at a time when most students were in class. 
 
 
 
 “There were fewer people out and about at that time,” Huff said. “Had it occurred between classes, there would have been thousands of people walking along the sidewalks and in the central campus area. 
 
 
 
 “We are very fortunate no one else was hurt,” he said. 
 
 
 
 Police haven’t released information about whether Comstock was believed to have had a gun or other weapon with him in the truck. Huff also declined to comment about whether Comstock’s father reported his son as being dangerous when he called police. 
 
 
 
 “That’s all part of the investigation,” Huff said. 
 
 
 
 Comstock's criminal history in Iowa includes a handful of minor charges, including disorderly conduct, drug possession, curfew and driving violations. 
 
 
 
 On her Facebook page, a woman who says she's Comstock's mother wrote on Monday, "My baby boy is gone after Ames police shot him this morning after a chase. Please take a moment to honor him today." 
 
 
 
 Shari Comstock goes on to say that she doesn't know why officers shot him "when he was unarmed" and they had him "blocked in." ||||| CLOSE An unidentified person on the Ames police radio dispatch twice suggested that police back off their pursuit of a teen who allegedly stole a pickup truck from the work site he and his father were working at on Monday.

 DES MOINES, Iowa -- An Ames, Iowa, police staffer twice suggested that an officer back off his pursuit of a 19-year-old man who allegedly stole a truck Monday from a work site where he and his father were working, according to dispatcher audio obtained by The Des Moines Register. 
 
 The officer, identified as Adam McPherson, continued his pursuit of Tyler Comstock onto the Iowa State University campus, according to the audio. 
 
 Minutes later, the truck Comstock was driving stopped, and officers commanded him to shut off the vehicle. Instead, Comstock revved the engine, and McPherson fired six rounds at the truck, police said. 
 
 Comstock died from two gunshot wounds, one each to his head and chest, according to the Iowa State Medical Examiner's office. 
 
 McPherson, an eight-year veteran of the Ames department, was placed on leave while the shooting is investigated. 
 
 Ames police have not yet reviewed whether the chase followed department policy, Cmdr. Geoff Huff said. An investigation into the shooting, led by the Iowa Division of Criminal Investigation, will be completed first, he said. 
 
 On the audio, an unidentified Ames police staffer can be heard saying that the driver's identity is known. 
 
 A copy of the department's chase policy, obtained by The Des Moines Register, requires ending pursuit "when the suspect's identity has been established to the point that later apprehension can be accomplished." 
 
 Huff said he could not comment on the dispatcher audio obtained by The Register. The audio is from Broadcastify, an Internet site that broadcasts dispatcher traffic. 
 
 "We have not released any audio or video about the incident," Huff said. "We don't know where they came from, so we wouldn't comment on them." 
 
 In the audio, an officer in pursuit of Comstock tells dispatch that the truck's driver "just rammed me, he just rammed my vehicle." A few seconds later the officer, who is not identified, says: "He blew the stoplight … he lost the trailer." 
 
 At that point, the unidentified police staffer tells the officer: "If he's that reckless coming into the college area, why don't you back off." 
 
 Moments later, the police staffer again suggests the officer cut off the pursuit. "We know the suspect. We can probably back it off." 
 
 On the audio, there's no indication that the officer responded to the suggestion. 
 
 On Monday, Huff had said police discussed ending their pursuit as it neared the ISU campus but decided to continue because of the driver's dangerous behavior. The driver had shown a "disregard for all pedestrians in the area," and police wanted to stop the truck before the driver hit anyone, Huff said. 
 
 Ames police Tuesday released a six-page policy on the pursuit of motor vehicles, created in 2004. According to the document, the policy requires: 
 
 -- Officers and supervisors involved in a chase to "continually evaluate whether or not the seriousness of the offense justifies continuing the pursuit." 
 
 -- The pursuit be ended if the officers or supervisors believe the danger created by a pursuit outweighs the capture of the suspect. 
 
 -- The pursuit be ended when the suspect's identity is confirmed and the suspect could be apprehended at a later time. 
 
 William Moulder, a law enforcement consultant and retired Des Moines police chief, said it's a standard rule in law enforcement not to shoot at a vehicle when the driver is inside, even if the vehicle is stopped. 
 
 "If the guy's in a car, it can presumably drop into gear and go," he said. "If you hit the driver, the car may continue moving and run into a pole or somebody, and you really increase the danger." 
 
 In an officer-involved shooting, the officer will have to explain whether he believed someone's life was in danger when he fired, Moulder said. Iowa law requires deadly force be used only to stop danger to another person. 
 
 When deciding whether to continue a chase, some departments have a policy that requires a police supervisor to monitor the chase, Moulder said. The supervisor then has the authority to call off the chase, if necessary. 
 
 Moulder cautioned that dispatch audio reveals only a portion of the events. A full investigation could reveal other details. 
 
 "It's one of those things, you can't really Monday-morning-quarterback it until you have all the facts," Moulder said.

– The Des Moines Register reports on a fatal police shooting this week, and a quote high up in the story from the victim's father pretty much tells the tragic tale: "He took off with my truck," recalls James Comstock. "I call the police, and they kill him. It was over a damn pack of cigarettes. I wouldn’t buy him none. And I lose my son for that." Comstock explains that his 19-year-old son, Tyler, took off with the truck after their argument, and he called police to teach him a lesson. Then things went horribly wrong. A police cruiser tried to pull Tyler over, but he refused to stop. At one point, he even rammed the officer's car. The chase led onto the campus of Iowa State University, and dispatch audio reveals that a police staffer twice recommended that officers end the pursuit, reports USA Today. They did not, and KCRG reports that pedestrians had to jump out of the path of the truck, which at one point was going against one-way traffic in the bike lane. Tyler eventually stopped the truck, but he kept revving the engine and refused orders to turn it off. At that point, an officer fired six times into the truck, killing him. The shooting remains under investigation. "He didn’t shut the damn truck off, so let’s fire six rounds at him?" asks Tyler's step-grandfather. "We’re confused, and we don’t understand." Police have said they feared for the public's safety if he took off again.
