DALLAS (AP)  Authorities have linked a second death to an electronic music festival in Dallas where they suspect a 22-year-old man took drugs, later began acting irrationally and died after running into freeway traffic on his way home.

Police in North Texas say Kyle Raymond Haigis of Sherman was struck by a tractor-trailer on U.S. 75 early Sunday after the Electric Daisy Carnival.

Howe police Chief John Cherry said the man’s friend told officers they bought drugs at the festival. On the ride home, Haigis became agitated and exited the vehicle after they pulled over.

A 19-year-old man who attended the concert died of a suspected overdose at a Dallas hospital Saturday.

Los Angeles banned the festival last year after a teenager died. The three-day event is in Las Vegas this weekend.
