BOSTON (AP) – Boston police were looking for two suspects Wednesday in the murder of a a 20-year-old mother killed last month at the same spot, on the same day and nearly the same hour, that her brother was slain four years ago.

Police announced they had arrest warrants charging Laron Lewis Richardson, 28, with murder and Steven Sayles, 29, with accessory after the fact to murder.

Richardson is from Boston’s Jamaica Plain neighborhood and Sayles from the Dorchester neighborhood. Both men should be considered dangerous and may be armed, police said.

Analicia Perry was killed July 22 while lighting candles at a makeshift shrine to her brother, Robert Perry, 26, who was fatally shot there in July 2002, according to police.

A suspect in that slaying was reportedly found, but days later he was himself shot to death.

Analicia Perry was a graduate of North Cambridge Catholic High School and had planned to attend Quincy College to study nursing, friends said. She had a 4-year-old daughter.

The family moved from the 366-unit Alice Taylor development soon after Robert was killed. The building is directly behind the Boston Police headquarters, in the shadow of Northeastern University and Wentworth Institute of Technology.
