Officers arrested and charged Jermaine Canada, 27, with first-degree murder. A resident called 911 around 9 a.m. on Monday and reported seeing a man matching the description of the gunman in the 2600 block of W. Camelback Road, police said.
"The children were not with him at the time he was taken into custody, and that was a great concern for us," said Detective Stacie Derge with the Phoenix Police Department. "We didn't know where those kids were, but thankfully the kids are OK and they are in the custody of their mother."
The man had a brief conversation with the 7-Eleven clerk around 2:15 a.m. and then opened fire while holding the 2-year-old child, killing the 62-year-old clerk, officers said. He then walked out of the store at 2651 W. Glendale Ave. with the children, who did not appear to be injured, police said.
