Separate shootings in Columbia Saturday left some in the area surprised, raising concerns over safety as the Howard County Police Department investigates.

The 17 year-old boy arrested in connection with the fatal shooting in Columbia will remain in the Howard County Detention Center. The teenager is charged with first-degree murder for killing 26-year-old Kendrick McLellan.

A Howard High School student was arrested at the school, accused of murdering a 26-year-old man found shot to death in a vehicle behind a Columbia office building, according to police.

An Ellicott City teen appeared in court for the first time Wednesday, facing a first-degree murder charge in the shooting death of a 26-year-old Baltimore man last week in Columbia. A Howard County judge denied the teen’s bail and ruled his case will remain in adult court due to the violent nature of the charges.
