James W. Calvert, Murder Suspect, On Lam With Son; Authorities Issue Amber Alert

Authorities in Tyler, Texas, have issued an Amber Alert for a 4-year-old boy who has been abducted by his dad, a murder suspect accused of killing the boy's mother.

Investigators say Jelena Radovanovic Sriraman, 30, was shot and killed around 12:10 p.m. Wednesday at her home by her ex-husband, James W. Calvert, 41. Authorities say he has allegedly kidnapped their 4-year-old child, Lucas Calvert, KLTV-TV reported.

Calvert is believed to be driving a gray or silver 2004 Buick LeSabre with license plate DP4 G858. He is believed to be armed and dangerous.

The missing child, Lucas, is described as being about 3-feet tall, weighing about 30-40 pounds with brown hair and brown eyes, according to KETK-TV. He was last seen wearing grey sweats, a blue sweatshirt, brown sandals and has silver caps on his teeth.

Sriraman has another child who was reportedly at school when Lucas was abducted and is safe, WFAA-TV reported.

Sriraman's pastor, Larry Craig of Southern Oaks Baptist Church, told the Tyler Morning Telegraph that Sriraman had recently been awarded custody of the children by a court.

Calvert had previously been charged with aggravated assault family violence in 1999, according to the Longview News-Journal.

Calvert has also been in jail on three charges of violating a protective order since 2009, the Dallas Morning News reported.

“We do believe that there were ongoing issues between the Calvert and the victim,” Tyler police spokesman Don Martin told the paper.

The Tyler Morning Telegraph reports another child of the slain woman was at school and is safe. The woman's pastor, Larry Craig of Southern Oaks Baptist Church, tells the newspaper Sriraman and Calvert had recently gone through a child-custody case in which she was awarded custody.

Pastor Craig said the church owns the home where the shooting occurred, and was letting Sriraman and her kids stay there while she went back to school and were assisting her as she prepared to move, KLTV-TV reported.

Anyone with information that might help authorities is asked to call the Tyler Police Department at 903-531-1000.
