No charges will be filed against a school bus driver involved in a fatal crash with a bicyclist in St. Paul, the Ramsey County attorney’s office said Friday.

Two witnesses reported the bus driver, Leland William Jacobs, had the right-of-way and the bicyclist, Alan “Al” Grahn” went through a red light and struck the bus, according to Steve Linders, a St. Paul police spokesman.

On May 9 at 2:10 p.m., the bus was in the intersection at Snelling and Summit avenues waiting for westbound traffic to clear so Jacobs could complete a left turn to go north on Snelling, Linders said of the witnesses’ reports.

“At some point, the light turned red and the westbound traffic cleared the intersection,” Linders said. “That’s when the bus driver began to turn north onto Snelling Avenue. At this point, the bicyclist rode into the intersection, through a red light and into the bus. Witnesses say the bicyclist never stopped at the red light.”

Grahn, 75, was heading west on Summit, according to police.

“Based on the facts presented to us by the St. Paul Police Department, we have determined that we cannot prove beyond a reasonable doubt that the driver operated the bus in a grossly negligent manner which is the legal standard required to bring a felony level criminal charge,” said Dennis Gerhardstein, Ramsey County attorney’s office spokesman.

Police do not plan to send the case to the city attorney’s office to consider lesser charges, Linders said.

Grahn, of Minneapolis, was an avid outdoorsman and grandfather who was devoted to his family, said his son, Andy Grahn. He had just finished lunch with friends from high school at Dixie’s restaurant on Grand Avenue and was heading home.

The crash happened after the bus left Ramsey Middle School. There were 30 students on the bus and some witnessed the crash. They were uninjured.

Andy Grahn said Friday that officials had not informed him about the investigation’s findings.

A memorial bike ride was held for Al Grahn on May 16 and his son said he was amazed to see the large turn-out.

“There were so many people that my dad knew … and so many people who he didn’t know who came out in support,” Andy Grahn said.

Summit Avenue has bike lanes in both directions, but given its unusual intersection with Snelling — a busy state highway — cycling advocates would like to see the city take things a step further by adding protected bike lanes.

A group of residents, Sustain Ward 3, have started an online petition calling on the city to separate bike lanes from traffic with permanent bollards on Summit Avenue.

“We believe it’s far past time to make Summit Avenue safer for everyone who uses it,” organizers wrote in the petition.

A memorial gathering for Al Grahn is planned for June 3 from 1 to 4 p.m. at Theodore Wirth Park Chalet. The family has asked that memorials be directed to an outdoor or environmental charity.
