Shooting of Sean Monterrosa


On June 2, 2020, Sean Monterrosa, a 22-year-old Latino American man, was fatally shot by Vallejo police officer Jarrett Tonn. Monterrosa was allegedly on his knees and had his hands above his waist when Tonn shot him through the windshield of his unmarked police pickup truck. The police later said Tonn shot him because he believed a hammer in Monterrosa's pocket was a gun. Monterrosa later died at a local hospital.
The event sparked outrage in the Bay Area, particularly in Vallejo, which has a long history of police violence, excessive force complaints, and high-profile killings, including the February 2019 shooting of Willie McCoy.

People and Entities involved

Sean Monterrosa was of Argentinean descent. He grew up in San Francisco and attended an arts high school. He had worked for a Boys & Girls Club. Less than an hour before Monterrosa was shot, he texted his sister a petition demanding justice for George Floyd, who was killed by Minneapolis police a week earlier. Monterrosa was laid to rest on June 19, 2020. Monterrosa had previously been arrested on suspicion of theft, shoplifting, shooting into a home, attempted murder, and weapons charges.
Jarett Tonn has been a police officer in the Vallejo Police Department since 2014, after working for the Galt Police Department from 2007 to 2014. Monterrosa's killing was the fourth time in five years that Jarrett Tonn had shot at a person while on duty, including two shootings within six weeks in 2017 and a shooting in 2015 where Tonn fired 18 times. None of the three prior shootings resulted in a death and Tonn was cleared of wrongdoing by internal investigations in each case. Fifteen days before the fatal shooting of Monterrosa, a lawsuit was filed against Tonn in Federal court alleging use of excessive force and violation of civil rights.
The Vallejo Police Department Over the last decade, Vallejo police have shot 32 people, 18 of whom were killed, in which time no officer has been fired for their role in a shooting. As of May 2019, the department had the highest per capita rate of police shootings in Northern California. Vallejo police killed people at a per capita rate over four times as high as neighboring city a city with a similar population and high violent crime rate.

Incident

Monterrosa was killed at 12:30 a.m. on June 2, while the city of Vallejo was under curfew in response to looting. Police did not reveal his death until a June 3 news conference. Police chief Shawny Williams said police were responding to a report of a possible looting at a branch of Walgreens and when officers arrived they saw 10 to 12 people in the parking lot. Two vehicles, a black sedan and a silver pickup truck, fled the area, resulting in a car chase where the black car rammed an officer's car and injured an officer.
Three detectives who were not involved in the chase arrived at the scene, in an unmarked pickup truck. Two detectives were in the front seat, and one was in the rear. As the truck arrived at the scene, the detective in the backseat mounted and aimed his rifle; he did not turn on the sound switch of
body camera he was wearing. Just as the truck came to a stop, the detective in the back seat, later determined to be Jarrett Tonn, fired a rifle five times, through the windshield of the vehicle. One bullet struck Monterrosa in the back of the head. Immediately upon exiting the truck Tonn was recorded saying "What did he point at us?" The driver responded "I don't know man." Tonn then shouted "Hey, he pointed a gun at us!" At no point in the immediate aftermath of the incident was the shooting officer separated from other involved officers.
The detective Tonn claimed Monterrosa appeared to be running towards the black sedan involved in the chase but he suddenly stopped, took a kneeling position, and placed his hands above his waist. No firearms were found with Monterrosa. The involved detectives claim that they mistook the end of a 15-inch hammer sticking out of his sweatshirt pocket for a gun.

Aftermath

Release of information

On June 2, 2020, at 4:08 am, police released a statement indicating that there had been an "officer-involved shooting," yet declined to offer specifics on whether it was fatal and who was involved. Monterrosa had been declared dead two and a half hours before that press conference took place. At 3:00 pm on the afternoon of June 3, 2020 the Vallejo police chief announced that the previously disclosed shooting involved an officer fatally shooting someone. When asked to explain the delay in informing the public that an officer had killed someone, the chief stated that at the time of the initial statement Monterrosa had not been pronounced dead. In media reports on June 10, 2020 the public learned that the police chief's statement on June 3rd was not accurate information.
In the later-released body-cam footage of the incident, Tonn is heard saying first that Monterrossa pointed something at the police vehicle, then saying that Monterrossa pointed a gun at the police vehicle. In a press conference on June 5, 2020, the police chief said that the officers saw Monterrossa running toward a car at the scene, that he stopped, took a kneeling position, and placed his hands above his waist, revealing what appeared to be the butt of a handgun. On June 5, the Vallejo police union released a statement, saying that Monterrosa “abruptly pivoted back around toward the officers, and crouched into a tactical shooting position,” that the hammer “appeared to be the butt of a gun, and that the officer fired, “as a last resort.”
The name of the officer involved was not released by the police department. The Bay Area News Group identified the shooter as Jarrett Tonn on June 5. On June 15, the Vallejo police union filed a temporary restraining order to prevent the release of the name of any officer involved in the killing. On June 16, the city of Vallejo announced it would oppose the motion in court and would “seek to defend the ity’s right to release the name of the officer at a time and through a method of its choosing.”
Police body camera footage was released several weeks after the shooting. The footage does not show Monterrosa before he was shot, but shows Tonn firing from inside his car before he had fully stopped his vehicle, detective tonn asked detective #1 driver, what did he point at us, driver stated I don't know man. Tonn also said that Monterrosa was running, tonn said "This is not what I fucking needed today!"

Civil suit

The Monterrosa family is being represented by civil rights and police brutality attorney John Burris. Burris has issued a statement condemning Tonn's overreaction as Monterrosa had done nothing to threaten the police and was not threatening anyone with a weapon, even if he had been armed with one. Burris said that "here is a 22-year-old kid who is now dead who appeared to be surrendering and he is shot down in cold blood." Burris has also announced that he intends to file a civil suit against the city of Vallejo. Following the release of the body camera footage Burris said the footage made clear that there had been "no de-escalation" and "no justification" for the use of lethal force, and noted that police officials had offered multiple conflicting accounts of the shooting.

Independent investigation

On June 5, California Attorney General Xavier Becerra announced an investigation into the Vallejo Police Department dating back to 2013. U.S. Representative Mike Thompson and Assemblyperson Tim Grayson had called for an independent investigation into the killing, with Grayson saying that "it is absolutely unacceptable that the public was forced to wait for over 24 hours to learn of the conditions of those involved in the shooting," regardless of the circumstances.

Reactions

Monterrosa's sisters have called for the release of body camera video of the killing of their brother by Vallejo police.
The San Francisco Board of Supervisors has passed a resolution urging the city of Vallejo to release the body camera video of the incident.
Protestors have gathered in Vallejo to ask for officers involved to be charged "to the fullest extent of the law" and to call for the release of body camera video.
