NFL legend Junior Seau was found dead in his home in Oceanside, CA … and a law enforcement source at the scene tells us cops believe he shot himself.
Seau was 43-years-old … and leaves behind 3 kids and an ex-wife.
Cops are currently at Seau’s home — located in San Diego County — and were seen talking with a man who was inside the house and appeared distraught.
We’re told Seau sent text messages to his ex-wife and 3 kids yesterday saying, “Love you.” We’re told they all responded and didn’t suspect anything was wrong. We’re told he last saw his kids 3 weeks ago.
Sources close to Seau tell us family members didn’t notice any signs of depression in recent weeks.
