A drive-by shooting in San Antonio de Escazú Sunday morning killed an 18-year-old woman and injured the 15-year-old boy she was with.
Investigators have not established a tentative motive.
The two victims were standing on a corner early Sunday when a vehicle drove by and someone inside fired multiple times at them, said investigators.
The woman was identified by the last names of Castro Solano. The boy was identified by the last name of Chavarría, said the Judicial Investigating Organization.
The boy was reported in serious condition in Hospital San Juan de Dios with a wound to the back.
San Antonio is several kilometers south and up the mountain from Escazú Centro. This type of criminal activity is unusual in the community.
