(Update: BU identifies student killed at marathon)

Boston University officials have identified one of the three people killed in Monday’s bombings at the Boston Marathon as a graduate student from China attending the school. Another BU grad student was injured and remained at a Boston hospital.

The school said Lu Lingzi (GRS’15), a graduate student in mathematics and statistics, was killed when she was standing with two friends near the finish line of the marathon when the bombs went off, BU said in a message on its website.  One of her friends was injured; the third was not harmed. The injured student was treated at Boston Medical Center and received a visit from BU’s Rev. Robert Hill, who reported that she had surgery both on Monday and Tuesday and that “is doing well.”

The two other people killed in the blast have been identified as an 8-year-old boy named Martin Richard of Dorchester, which is a neighborhood in Boston, and 29-year-old Krystle Campbell of Arlington, Mass.  Martin’s mother and sister were seriously injured.

BU is offering counseling services to students.
