A tenth victim of the Feb. 7 Imperial Sugar refinery blast in Port Wentworth, Georgia, died Friday, according to the Associated Press.

The victim, whose identity was being withheld pending notification of family members, died at the Joseph M. Still Burn Center at Doctors Hospital in Augusta, Georgia. Thirteen patients from the explosion remain in the burn center in critical condition and two others are in serious condition, said Beth Frits, spokeswoman for the hospital.

Meanwhile, a memorial service for those killed in the explosion or died as a result of the explosion was held in Savannah on Saturday.

The explosion destroyed the packaging area where workers poured sugar into bags sold under the Dixie Crystals brand. The refinery itself, used to turn raw sugar into consumer-ready crystals, remains shut down.
