Philadelphia's chief medical examiner has testified in the murder trial of an abortion provider, saying he can't be sure if any babies were born alive.
Dr. Sam Gulino testified that he examined 47 fetuses recovered from a clinic run by Dr. Kermit Gosnell. Gosnell is charged with killing a patient and seven babies.
Gulino said many of the bodies had been stored in a freezer, complicating his examinations. Gulino said he believes that two fetuses he examined were beyond Pennsylvania's 24-week limit.
Prosecutors said Gosnell or his untrained staff killed at least seven babies born alive. Gosnell's defense lawyer has denied the charge.
Another city abortion provider also testified, drawing stark comparisons between his work and Gosnell's.
Gosnell is also accused of performing illegal, late-term abortions and running a dangerously outdated clinic.
