GARY | Gary police believe whoever killed a 13-month-old boy and wounded his mother in a Monday night carjacking did not work alone, police said Wednesday.

(Listen to the 911 tapes.)

The boy's father was being held as a "person of interest" in the case Wednesday, while Gary police released recordings of 911 calls made after the shooting.

During one of the calls, a panicked woman identifies herself as Kwana Shaw's friend and pleads for help.

"They just stole her truck, and her baby in it," she cries into the phone. "I think he shot her. Oh my god," she says, "her baby in the truck."

"Please hurry up," she cries.

Both of the callers said the shooting took place at Lancaster Apartments at 21st Avenue and Virginia Street.

Kwana Shaw, 29, was putting her son into her sport utility vehicle in the 500 block of West 21st in Gary when a man approached her and shot her, Gary police Cmdr. Samuel Roberts said.

Police later found the boy wounded in the SUV at the intersection of 17th Avenue and Virginia Street. The boy was taken to the hospital and the SUV was taken to the Lake County crime lab for analysis, Roberts said.

Josiah Shaw, of the 9600 block of West 77th Street in Schererville, suffered gunshot wounds to the chin and pelvis, and was pronounced dead at the Methodist Hospitals Northlake Campus in Gary.

Kwana Shaw survived the shooting, but was critically injured. More information on her condition was not available Thursday.

Josiah Shaw's father, Terry L. Bethel, 34, of Portage, was picked up there on a failure-to-appear traffic warrant and was in custody of Porter County authorities.

"Information we received from people led us to want to talk to him more closely," Roberts said.

Roberts said Bethel works at the ArcelorMittal Burns Harbor plant, and there is a "50-50 chance" that charges will be filed against him in the shootings.

A woman who answered the door at Bethel's listed address said she had no comment. The home, a bi-level in the newer Southfield Estates subdivision, had a "for sale" sign in the front yard.

There are no funeral arrangements yet for Josiah Shaw as his mother recovers.

As his legal custodian, Kwana Shaw would have to make arrangements for another person to release him, according to Chief Deputy Coroner Jeff Wells.

Kwana Shaw had not been told as of Wednesday afternoon that her son had died, the family's pastor said.

Pastor Tommy Kimble, who baptized Josiah Shaw, said he likely will handle services at Gary's Centennial United Methodist Church, 777 Rhode Island St.

Kimble returned to the hospital Wednesday afternoon to visit and pray with the Shaw family, which he has done all week. Kwana, who lost a lot of blood in her shooting, was scheduled to undergo another surgery Wednesday, he said.

The Shaw family grew up in Gary and continued to attend Centennial after moving to Schererville. The church threw Kwana Shaw a baby shower before Josiah's arrival.

"It took a big toll on us," Kimble said of the shootings. "But we're a praying church."

Kimble described Kwana Shaw as "quiet and very loving," and said the 1996 Horace Mann graduate had been considering going to college. An orientation night scheduled for Monday had been cancelled, freeing her to visit friends in Gary, Kimble said.
