The family of a baby boy delivered moments after his mother was shot and killed at a home near Coolidge last week had planned to seek the public's help with the infant's medical expenses.

But now, the family of the baby, named Cornell Angel Bollinger, must plan his funeral as well as his mother's.

And Ronald James Thompson, the Coolidge man accused of shooting the mother, Angel Bollinger, 21, now is facing additional charges, according to authorities.

Cornell, who was born two months premature at Casa Grande Regional Medical Center on Feb. 5, died at 1:30 a.m. Thursday morning, according to Lt. Tamatha Villar, spokeswoman for the Pinal County Sheriff's Office.

Cornell weighed just a little more than 2 pounds, his aunt, Tina Lockwood, told the Tribune on Thursday.

"He just couldn't hold on," said Lockwood, a Valley resident. "Our family is devastated. He's now with his mother. If that's what God wants, then that's what is meant to be."

The baby's mother was pronounced dead on arrival at Casa Grande Regional Medical Center, shortly after she was shot about 10:30 p.m. on Feb. 5 during an argument that escalated at a residence in the 1000 block of Martin Road in an unincorporated area south of Coolidge, according to Villar.

Bollinger's boyfriend, Harvey Rushing Jr., 23, of Coolidge, was shot in the arm during the argument, but was able to drive himself and Bollinger into downtown Coolidge, where he stopped the car across from the Galloping Goose Bar, at 1980 S. Arizona Blvd., before they were transported to the hospital, authorities said.

Rushing's injuries were not life-threatening, and he is expected to recover, Villar said.

Thompson, the man arrested on suspicion of first-degree murder Feb. 5, now is facing a second charge of first-degree murder as well as a charge of attempted murder, according to information from the Pinal County Sheriff's Office.

The additional charges were recommended by the Pinal County Sheriff's Office on Thursday, and a county grand jury will consider them sometime next week, Villar said.

Thompson, 31, had been released from the Pinal County Jail on an $11,538 bond on Feb. 3, two days before the slayings, according to information from the Pinal County Jail. Thompson had been scheduled to begin a jury trial on March 10 in Pinal County Superior Court on charges of aggravated robbery and aggravated assault with serious physical injury and theft, according to the court's records.

Thompson again is being held in the Pinal County Jail, but bond information was not available.

Investigators are not releasing a motive at this time because sheriff's deputies are seeking to question at least two more people of interest in connection with the slayings, Villar said.

Of Bollinger and her baby's death, Villar said, "It's a very unfortunate tragedy and not something any of us wish to deal with."
