Here's how to the help crossing guard Andrew Tyler, who lost his left leg after a hit-and-run driver crashed into him

Community support is pouring in to help 71-year-old crossing guard Andrew Tyler, as Milwaukee police continue to search for the driver who hit him last week.

Tyler was walking to his post at Kluge Elementary School about 6:30 a.m. Friday when he was hit by a burgundy car in the 7200 block of W. Carmen Ave.

The driver sped off and Tyler suffered serious injuries and was taken to a hospital, Milwaukee police said.

In the meantime, his family has set up an online donation page to help with expenses. As of Wednesday morning, more than $2,000 had been donated.

Tyler remained in critical condition this week. After experiencing kidney failure, his left leg was amputated, according to a post on the donation page.

"He was simply walking to work to protect and keep Milwaukee children safe. His life is changed forever," his family wrote.

Tyler has served as a school crossing guard through the Milwaukee Police Department for nine years, joining after his retirement from Delphi Automotive.

Milwaukee police are seeking the driver and the car, a burgundy, four-door 1997-2001 Buick Park Avenue or LeSabre.
