Tristan Beaudette was found bleeding from a head wound inside a tent with his young daughters after police responded to a report of shots fired, KCAL-TV reports. The children, ages 2 and 4, were not injured, police said.

“The theory we are working with is he was shot inside the tent,” Los Angeles County Sheriff’s Department Lieutenant Rodney Moore told the Los Angeles Times. “The children were inside the tent, too. We are working this as a homicide at this point. We are gathering evidence. … It will take some time.”

According to the Los Angeles County Sheriff’s Department, the shooting happened on Friday, June 22, 2018, at 4:44 a.m. in the 1900 block of Las Virgenes Road in Calabasas, in the Malibu Creek State Park. “Homicide detectives are confirming that at the time of the shooting, the victim was inside the tent with his two children.” The LASD added, “Homicide detectives have learned that deputies from Lost Hills Sheriff’s Station responded to the location regarding a shots fired call. When deputies arrived they located the male adult victim who had sustained at least one gunshot wound to his upper torso. He was pronounced dead at the scene.”

The LASD said there is no suspect information to release and there is no known motive for the crime. The investigation is ongoing.

“It’s pretty secluded,” a woman who was camping near Beaudette’s family told KCAL. “It’s pretty spread out. It’s pretty quiet. I wouldn’t expect something [like this] to happen.”

There are 63 campsites at the Malibu Creek State Park area where the shooting occurred and they are believed to have been occupied at the time of Beaudette’s death. The campsites will be closed this week while police investigate the shooting, authorities said. “Campgrounds at Malibu Creek State Park were closed Friday due to an ongoing investigation by the Los Angeles County Sheriff’s Department. To ensure public safety, all camping reservations for the park have been cancelled through June 28,” California State Parks said on Twitter.

A woman who was camping at Malibu Creek State Park in January 2017 told KCAL-TV that she heard a loud noise about 5 a.m. and later found a bullet in the back of her car. She posted about the incident on Facebook and said she reported it to the sheriff’s department. But the LASD said in its press release, “Homicide detectives are aware there have been other shootings near the location in the past, however there is no evidence that suggests this incident is related to any prior shootings near the location.”

Since Beaudette’s shooting deth, others have come forward with information about shooting incidents at the state park, CNN reports. Investigators are now looking into whether seven shootings are connected to Beaudette’s death. Those shootings date back to November 2016. But police still say there is no evidence the incidents are connected, though they aren’t ruling it out.

Detectives say the shootings occurred November 3 and November 9 in 2016, January 7, June 6, July 22 and July 30 in 2017 and on June 18, 2018. None of those shootings were fatal.

“There were a number of incidents but they were over an extended period of time. The pattern at this point certainly is not clear, if there is one at all,” Sheriff Jim McDonnell said this week, according to the Ventura County Star.

Tristan was the greatest friend you could ever ask for, a talented scientist, an amazing father to his beautiful daughters and a devoted loving husband,” Daniel Poulsen wrote on Facebook. “He was the most genuine kind person you’d ever meet. I treasure every memory of the annual hiking trips we went on together with the guys and it will never be the same without you. I will never forget you.
