Baltimore police have charged a 21-year-old man with first-degree murder in last month's shooting of a 19-year-old woman who authorities described as an innocent bystander who had just graduated high school and was planning to attend college to study nursing.

Tanise Ervin was one of three people shot March 12 outside a carryout in the 900 block of Gorsuch Ave. in Better Waverly, steps away from where she lived with her mother in Serenity House, part of a women's shelter run by the Sisters of Mercy and Sisters of Notre Dame.

Police spokesman Anthony Guglielmi identified the suspect as James Cureton, of the 5200 block of Anthony Lane. He is being held without bail on unrelated armed robbery, assault and gun charges at the Baltimore City Detention Center, awaiting trial on those charges, scheduled for May 3.

Guglielmi said Cureton has been charged in an arrest warrant, which is in the process of being served. News of the arrest first appeared in an online neighborhood newsletter after police briefed North Baltimore residents on the case.
