Now to that frightening rise in carjackings. Teenagers behind many of them. Two more teens now facing charges in Washington, D.C. After a pair of attacks on Friday. Experts saying the pandemic is partly to plane. Our erielle reshef has more. Reporter: This morning, law enforcement warning of an alarming spike in carjackings nationwide. In Los Angeles Monday a suspect stealing a car colliding with another vehicle then slamming into a tree. And earlier this month barstool sports founder Dave Portnoy was filming a video catching a car theft in progress on camera. That guy just got carjacked. Reporter: In January a suspect assaulting a woman at a Maryland gas station then taking off. And now authorities across the country tracking a disturbing trend during the pandemic, a growing number of carjackings perpetrated by teenagers. Two female suspects just 13 and 15 years old charged with felony murder and armed carjacking in Washington, D.C. After they allegedly used a stun gun on 66-year-old Uber eats drive Mohamed Anwar causing a crash that led to his death. It's more than tragic. I don't even know that that word describes what happened. It's senseless. Reporter: Just days after that horrifying incident two 13-year-olds also arrested in D.C. In connection with two separate armed carjackings. Authorities say with more kids at home and unsupervised during the pandemic, these crimes are skyrocketing. In my opinion the rise was caused by basically America shutting down because of covid. Gave the kids a lot more opportunity, a lot more free time on their hands. Reporter: The number of carjackings from Washington, D.C. Doubling from 142 to 345 in 2020. The same in Chicago where authorities say carjackings reached a rate of about four per day and in Minneapolis, 405 carjackings reported in 2020. That's triple the previous year. Minneapolis police saying they have seen a disproportionate number of juveniles involved in these crimes. They don't think about the future or really the consequences. It's just like one thing leads to another and so people get hurt and people die. Reporter: And authorities say car jacksonings can happen anywhere but the most commonplaces are atms, garages and gas stations. Experts say if you are approached in one of these circumstances you should give up your car and get as far away as possible. Your car obviously can be replaced and you can't. Guys. Always something good to keep in mind, erielle. Thank you.
