Sadly, this is business as usual in Mexico.
Read a couple of news articles about the incident and apparently the plane took off from Venezuela with no flight plan and transponder turned off and was picked up by Mexican radar before crossing the border, two Mexican Air Force E-145 AWACS were scrambled as well as a T-6 Texan which ultimately ended up intercepting the plane and tried making radio contact with them to no avail. Also says visual signs were used by the MAF pilot but ignored by the HS125 crew, which ended up landing on a highway where they had a truck waiting for them, set the plane on fire and fled. Also they mention a helicopter was deployed but only after the plane had already landed. Crew apparently ditched the truck and ran into the jungle before authorities arrived.
Here's one of the source articles in Spanish:
