BRADENTON, Fla. (AP) - A quadriplegic teen has been sentenced to life in prison for killing a woman during a robbery at a Bradenton home.

A Manatee County judge sentenced 19-year-old Ta Heem Blake Thursday, after a jury found him guilty of first-degree murder and other charges.

Authorities say Blake and Marquis Sanders broke into the home in February 2009. Blake reportedly shot 55-year-old Maria Lerma, who died at the scene, and her boyfriend, who later recovered.

Lerma's son fired at Blake, severing his spinal cord. Police found him at the scene, just feet from the murder weapon.

Blake's attorney argued that evidence had been moved around at the scene.

Sanders was convicted of first-degree murder and armed burglary in April. He was sentenced to life.
