The suspect, 19-year-old Kamau Thomas, Jr., of Carrick, was taken into custody Sunday night.

According to court papers, Thomas said he was in the area for a fight between two women. While he was there, he claimed another man made threatening gestures towards him. He claims the man had shot at him about a month ago and believed he had a gun at the fight.

After the fight broke up, Thomas said he returned to the area with the intention to scare off the other man.

Thomas reportedly told police he fired a shot into the air towards the roof of the home and when he brought the gun down the trigger was “sensitive” and the gun “started going crazy, and kept going off until (the magazine) was empty.”

Meanwhile, family, friends and neighbors held a vigil for the girl Monday night.

A prayer vigil will be held at Lighthouse Church from 6 p.m. to 7 p.m. Tuesday.
