The Latest on a car-and-knife attack at Ohio State University (all times local):

4:15 p.m.

A preliminary autopsy shows the attacker at Ohio State University died from gunshots to the head and chest.

A campus police officer shot the Somali-born student within a minute of his car-and-knife attack that left 11 hurt on Monday morning.

The coroner's office in Columbus said Wednesday that it could take eight more weeks before it can issue a final report on the death of Ohio State student Abdul Razak Ali Artan.

Investigators said Wednesday that the 18-year-old bought a knife on the morning of the rampage, but it's not clear if that's the weapon he used.

The FBI also says the investigation has not found that anyone else was involved in the attack or the planning of it.

Authorities are looking into whether the attack is linked to terrorism.

The FBI says a Somali-born student who carried out a car-and-knife attack at Ohio State University may have been inspired by the Islamic State group along with a former al-Qaida leader.

Law enforcement officials said Wednesday that it's too soon to say the rampage that hurt 11 people on Monday was terrorism.

The FBI says it is looking to verify whether Ohio State student Abdul Razak Ali Artan posted rantings on Facebook about U.S. interference in Muslim lands on the morning of the attack.

Police also say Artan bought a knife before the attack but do not know if that was the weapon he used.

The 18-year-old was fatally shot by a police officer shortly after driving into pedestrians and then slashing people with a knife.

Ohio State University students are continuing to offer messages of support following an attack on campus that injured nearly a dozen people.

All four panels of a two-sided board in the student union were filled with messages Wednesday, two days after 11 people were hurt in a car-and-knife attack carried out by OSU student Abdul Razak Ali Artan.

Writers using markers have contributed Bible verses, famous quotations and well-wishes to both the victims and police.

A number of students stopped by Wednesday to check out the board. Around them, a tour guide led prospective students and their parents out into the drizzling morning.

Artan was fatally shot Monday morning by a police officer shortly after the attack began.

Columbus police planned an update on the investigation later Wednesday.
