Officer Killed On Duty Honored by Police Force in Widow's Maternity Photo Shoot

— -- A widow, who lost her police officer husband in the line of duty while she was expecting, decided to honor him in a maternity photo shoot that's gone viral.

Officer Allen Jacobs died March 18 in Greenville, South Carolina.

His widow Meghan Jacobs is pregnant with their first child -- a baby girl to be named Lennox -- who is due in July.

To honor her late husband, Meghan Jacobs, with the help of a friend of more than 15 years, photographer Jessie Ellex, planned a maternity photo shoot that resulted in more than 600 photos.

"The tone of photo shoot was very mixed," Ellex, 29, told ABC News. "It was, of course, very somber, but bittersweet, knowing Meghan and Lennox have the support of the Greenville Police Department."

Ellex said the six-hour photo shoot started with just Meghan Jacobs and her mother, but they were later joined by officers.

"When the police officers met us around 7:30 [p.m.] all I could do was fight back tears. But we all pushed through," she recalled.

In many of the photos, Allen Jacobs' fellow officers and a police dog posed behind the widow. The photo shoot also featured her late husband's patrol car, his uniform, his badge and even the flag that had been on his casket.

In a caption on Facebook, Ellex noted that the "flag was never disrespected and never touched the ground."

Ellex said Meghan enjoyed the photos and that she is relieved because "Meghan is like a sister to me, so when she met Allen he became an important part of my life just like Meghan."
