(PRINCE GEORGE’S COUNTY, Md.) — Officials in one Maryland county said they are going to temporarily enforce a state curfew for teens amid a “troubling” increase in juvenile arrests.

Prince George’s County police officers have arrested an “eye-popping” 430 juveniles so far this year — more than double the number from this time last year, county executive Angela Alsobrooks told reporters during a press briefing Monday.

Carjacking is one area of particular concern, officials said. Eighty-four juveniles have been arrested for carjackings this year, half of whom were under the age of 15, she said. Among the 84 arrested, 34 had prior arrests for a violent crime or gun offense, she said.

“At this point, these kids don’t just need a hug, they also need to be held accountable,” Alsobrooks said. “I know this isn’t the popular thing to say, but the truth of the matter is, it’s a fair question: Where are their parents? Where are the aunties? Where are the uncles and other family members who are responsible for them?”

Prince George’s County Police Chief Malik Aziz called the number of juvenile arrests “shocking” and a “significant” jump from last year.

“The vast number of juveniles are out doing the right thing and living a meaningful and positive life in Prince George’s County,” he said during Monday’s press briefing, calling those who are committing crimes “outliers.”

“We can’t arrest our way out of this,” he added.

The curfew was last strongly enforced in 1995, though Alsobrooks said they “feel that the facts and circumstances warrant doing so again.”

The state law requires teens under 17 to be off the streets between the hours of 10 p.m. and 5 a.m. Sunday through Thursday and between 11:59 p.m. and 5 a.m. on Fridays and Saturdays, unless accompanied by an adult or if an exception applies, Alsobrooks said.

The county, which is located in the greater Washington, D.C., area, will begin stricter enforcement of the law starting this weekend for at least 30 days, Alsobrooks said. Parents will receive a warning for the first offense, though repeated offenses could see fines up to $250 and children could be released to the Department of Social Services if parents fail to respond, she said.

“Simply put, the enforcement of this law is to protect our children,” Alsobrooks said. “Children 17 years old and younger are not legally responsible for themselves. Neither are police. Their parents are responsible and their families are responsible for keeping them safe. We need everyone working to protect our children.”

Alsobrooks said she sees the curfew as one part of a “toolbox” to keep the community safe, alongside mental health services at schools and a summer youth enrichment program.

The county executive said she is seeking an emergency meeting with the Department of Juvenile Services and will continue to work with the court system to understand “how these kids are being held accountable.”

Prince George’s County State’s Attorney Aisha Braveboy, who was not present at the briefing, defended her office’s record on convictions at a later news conference.

“We absolutely hold people accountable for serious crimes,” Braveboy said Monday, calling the number of juveniles committing carjackings “outrageous,” according to Washington, D.C., radio station WTOP.

Officials in Philadelphia have also implemented a modified curfew for minors in recent weeks in an attempt to keep young people off the streets and safe during a high-crime season. Through Sept. 29, those between the ages of 14 and 17 are required to be home by 10 p.m. Previously, the latest some teenagers were able to be out was midnight. Those under 13 are required to be home by 9:30 p.m.

For those found violating the curfew, Philadelphia police will attempt to reunite them with their families at home or a precinct or bring them to one of several community centers that have been established during the curfew.

(SCOTTSDALE, Ariz.) — Three hikers died and several were injured over the holiday weekend in Arizona and Utah. Several hikers in Arizona suffered heat exhaustion as excessive heat gripped the West Coast.

A hiker in their 20s died and five others suffered heat emergencies while hiking a trail in Cave Creek, Arizona, Wednesday after running out of water and getting lost on the trails, according to the Scottsdale Fire Department.

The hikers, who were all locals, were removed from the trails by helicopter after emergency responders discovered they were about 4.5 miles from the trailhead, a representative from the fire department told ABC News.

The hiker who died was taken to a local hospital where he died due to heat stroke. The five injured hikers were given fluids and treated on the scene for about an hour before being cleared, according to the fire department.

Also in Arizona, a backpacker was reported dead in Grand Canyon National Park Sunday at around 7:30 p.m. local time. The backpacker has been identified as 59-year-old Delphine Martinez, who was on a multi-day trip, according to the National Park Service.

Martinez was hiking down the Thunder River Trail on Sunday when she became disoriented and later unconscious. Trip members tried to resuscitate Martinez, but were unsuccessful, according to NPS. NPS and the Coconino County Medical Examiner are investigating Martinez’s death and have not released any additional information.

According to the National Park Service, temperatures in the inner canyon were over 100 degrees, with the high temperature at Phantom Ranch around 115 degrees. Park rangers at Grand Canyon National Park advised visitors against hiking in the inner canyon during the heat of the day between 10 a.m. and 4 p.m., saying the heat can cause “serious health risks including heat exhaustion, heat stroke, hyponatremia and death,” according to the National Park Service.

Separately, a 45-year-old hiker in Utah fell to their death Saturday after going missing while climbing near the mouth of the American Fork Canyon, the Utah County Sheriff’s office said in a statement.

The man, identified as Thomas James Rawe, texted a friend asking him to pick him up near the canyon in 45 minutes. Rawe was hiking or climbing in the area and was on his way down. He sent a picture showing the the steep terrain and the fee booth where the two were supposed to meet up.

At the agreed upon time, the friend arrived and Rawe did not. Rawe had said his phone battery was at 1%, so the friend was not initially surprised to not hear from Rawe, according to the sheriff’s office.

At around 9 p.m. local time, deputies with the Utah County Sheriff’s Office received a report of a man missing while climbing near the canyon. The Utah County Sheriff’s Office Search and Rescue team responded and searched for a couple of hours, but because the terrain is dangerous, they called off the operation for the night. They returned early Sunday morning and called for assistance from the Utah Department of Public Safety and one of their helicopters, according to the sheriff’s office.

A helicopter crew member found what they suspected was the body of Rawe on a very steep, rocky slope, shortly after arriving. A Search and Rescue team member was then flown to the area to confirm the body was Rawe and that he was dead. Another volunteer was then flown to the area to secure the body from falling further down the mountain before it was prepared and hoisted to a nearby parking lot by the DPS helicopter crew, according to officials.

While officials are unsure what caused the fall, they said it is likely he “lost his footing or stumbled, then fell and tumbled several hundred feet down the steep slope.”
