Anthony Crawford pleaded guilty to a first-degree murder charge in connection with the September 2018 death of 35-year-old Wendy Karina Martinez

A homeless man accused of killing a bride-to-be as she jogged two blocks from her home in Washington DC pleaded guilty to murder on Friday.

Anthony Crawford pleaded guilty to a first-degree murder charge in connection with the September 2018 death of 35-year-old Wendy Karina Martinez.

Martinez, 35, was killed while running through a typically safe neighborhood last year. Crawford was arrested for her murder the following day.

Prosecutors said the 23-year-old stole a kitchen knife from a grocery store and then attacked Martinez while she was running in the Logan Circle neighborhood.

The plea agreement calls for a sentence of 30 years and a fine of up to $250,000.

As part of the plea deal, Crawford will also have to contribute between $100 and $5,000 to the Victims of Violent Crime Compensation Fund.

On the day of the attack, Martinez was out for an evening run when she was attacked by the knife-wielding male stranger at the intersection of 11th and P streets.

The mortally wounded Martinez ran into a nearby Chinese restaurant for help and video, obtained by Fox News, showed her run in as blood gushed from a laceration to her neck.

While some ran away from the horrific scene, other patrons rushed to her side. Tragically, she was taken to hospital, where she was pronounced dead.

The Georgetown graduate had just become engaged just last week, according to her heartbroken family, with a storybook proposal and a emerald ring.

'She got up and she ran into this restaurant and asked for help. That makes us so proud.'

Martinez lived not far from the crime scene and was an avid jogger known to run for miles.

A spokesperson for the Martinez family said on Friday: 'It's a difficult emotion to describe, its a heavy dose of sadness because it does nothing to bring Wendy back or make us whole.

'At the same time, it does provide some peace knowing he'll be off the streets, and we're grateful for that.'
