The 2-year-old girl shot and killed in her mother’s arms and the 11-month-old boy struck by four bullets a day earlier in Philadelphia were identified — as the city offered a $30,000 reward for information in each case.

Nikolette Rivera, 2, died Sunday when a gunman using a rifle fired into her home in North Philadelphia and hit her in the back of the head, the local CBS outlet reported.

Less than 24 hours earlier and about two miles away, Yazeem Jenkins, 11 months, was hit in the head, neck and buttocks while in the backseat of a moving car.

He was in critical condition on Monday.

“The prognosis is that there is no chance for full recovery for that child. If the child survives, he’ll most likely be quadriplegic,” Captain Nicholas Brown told WPVI-TV.

No arrests had been made as of Tuesday.

Nikolette’s 24-year-old mother was shot once in the right side of the head and once in the back and was in stable condition at an area hospital.

A 33-year-old contractor doing work inside the home at the time was hit in the stomach and was in critical condition.

The toddler was pronounced dead at the scene. She was going to be a baby shark for Halloween, according to an NBC10 Philadelphia reporter who posted a video of the girl in her adorable yellow costume.

“I knew her for a short time of her life,” Amelie Pagan, Nikolette’s great aunt, told the outlet. “She made an impact. She was awesome.”

“The children, these kids that are innocent and they’re dropping like flies,” she added.
