Preliminary hearings were held today for four people charged with operating a methamphetamine lab out of a home in Bethlehem.

Daniel Houser and Davina Bowler waived their hearings while charges against Elaine Noone and Jeffrey Caulfield were held for court.

They're all charged with operating a meth lab out of Noone's home on Greenleaf Street.

Investigators were planning to search the home in March, but it exploded and caught fire hours before they got there.

Seven people, including two police officers, were hurt.

All of the suspects will be formally arraigned in August.
