Dallas police found two children and two adults shot to death Tuesday afternoon at a hotel in Far North Dallas, authorities said.

Officers were called about 3:10 p.m. Tuesday to the scene of the Staybridge Suites near Keller Springs Road and the Dallas North Tollway, just east of the border between Dallas and the town of Addison.

When officers arrived, they found a man, woman and two children all dead of obvious gunshot wounds, Dallas Police Chief U. Reneé Hall said at a news conference Tuesday.

Police identified the two adults Tuesday as 41-year-old Charles Schoenfeld and 31-year-old Brittany Howard. The two children, both boys, were identified by the Dallas County medical examiner’s office as 9-year-old Noah Schoenfeld and 12-year-old Charles Schoenfeld II.

Hotel management told police that the four people had been staying at the hotel for about a week. Their stay expired Tuesday, and when management tried to enter the room, they heard a gunshot go off and called police, Hall said.

A weapon was recovered from the room, she said.

Hall said that investigators haven’t determined the circumstances surrounding the shooting but that they’re investigating the possibility that it was a murder-suicide.

“This is the hardest part of the job, to see lives lost, and especially children,” Hall told reporters. “So it’s a tough day. It’s a tough day whenever we lose a life, and today is no different. The sadness continues.”

Homicide detectives were gathering information at the scene Tuesday evening. Crime scene tape and about a dozen police cars, both marked and unmarked, surrounded the hotel.

A tow truck hauled off a Subaru Outback with a Florida license plate about 5:50 p.m. ​A Dallas officer was seen speaking to the tow truck operator before the SUV was removed from the hotel parking lot.

Officers began removing crime scene tape around 7 p.m., as authorities gradually left the scene.

Jeremy Remy, a hotel guest, stood nearby talking on his phone as he tried to make sense of the police presence.

Remy has lived at the hotel off and on for about a year. He said the shooting was a big disruption in what is normally a peaceful hotel.

“The worst I ever heard was probably a wreck of a fender bender,” he said. “Other than that, this has always been a good area to me. That’s why I stay over here.”

He was asleep during the shooting, but the sound of helicopters woke him up. He planned to eat dinner during an event at the hotel, but it was canceled, he said.

That’s when he went outside and saw police tape.

“It’s sad. I’m not going to quit staying here, but it’s sad,” he said. “You hate to hear it.”
