ALLENTOWN, Pa. -

A man and a teenager are heading to trial in connection with a double homicide in Allentown.

Homicide and other charges were bound over for court Tuesday in a preliminary hearing for John Boyd and Tykweis Wade.

They are charged in the killings of Steven Santiago and Adrian Ramirez. The two were gunned down in front of their home on South Hall Street in Allentown in December.

A dispute over an affair, and possibly drugs, led to the crime, police said.
